  text: This work discusses the additive manufacturing of an axicon lens using cyclic
    olefin copolymer (TOPAS), and its characterization between 100 GHz and 300 GHz.
    The proposed manufacturing process followed by dip-coating post-processing provides
    an improved surface finish. Additionally, the terahertz output of the lens remains
    intact over the entire frequency range.

  text: Additive manufacturing (AM) paves the way for low-cost production of optical
    and terahertz (THz) components such as waveguides, fibers, and lenses [1]–[3].
    This work addresses the fabrication and THz characterization of a 3D-printed waveguide
    composed of cyclic olefin copolymer (TOPAS). Such a waveguide is a convenient
    and inexpensive tool in the development of THz interconnects, and in applications
    such as biomedical sensing.

  text: This article discusses the additive manufacturing and post-processing of axicons,
    and their performance evaluation using attenuation and near-field-measurements
    based fundamental techniques. The axicons are manufactured using the materials
    cyclic olefin copolymer (TOPAS) and polymethyl methacrylate (PMMA), for their
    respective use in terahertz and near-infrared applications. An emphasis is placed
    on the dip-coating-based post-processing. Interval dipping and intermittent hardening
    lead to excellent surface finish and transparency in case of additively-manufactured
    near-infrared axicons. The dip-coated samples exhibit surface roughness of sub
    10nm, and a uniformly distributed thin layer coating over the axicon surface.
    In addition to the improved surface finish and transparency, the coatings are
    also closely matched in refractive index to the axicon material. Such post-processed
    axicons pave the way for rapid-prototyping and production.

  text: The use of additive manufacturing for rapid prototyping of near-infrared and
    terahertz components provides seamless and error-free production. This article
    discusses the additive manufacturing and post-processing of axicons and their
    performance evaluation using attenuation and near-field-measurements based fundamental
    techniques. The axicons are manufactured using the materials cyclic olefin copolymer
    (TOPAS) and polymethyl methacrylate (PMMA), for their respective use in terahertz
    and near-infrared applications. The optical and terahertz components manufactured
    using traditional 3D-printing processes, e.g., fused filament fabrication or stereolithography
    apparatus exhibit high surface roughness in the range of 15 ± 2.5 µm, resulting
    in undesired propagation and scattering in the near infrared wavelengths. This
    research work proposes an economical post-processing technique for additively
    manufactured terahertz and near-infrared axicons for applications in multispectral
    characterization, e.g., bio-sensing. The authors used an enhanced method of dip-coating,
    which involves interval dipping and intermittent hardening to achieve better surface
    finish. An emphasis is placed on interval dipping and intermittent hardening,
    which lead to excellent transparency in case of additively-manufactured near-infrared
    axicons. The dip-coated samples exhibit surface roughness below 10 nm. With the
    use of heated resin material as the coating layer, due to reduced viscosity, the
    resin material distributes uniformly over the surface of the 3D-printed terahertz
    and near-infrared axicons. The authors also observed that the DOF length deviation
    between unprocessed and enhanced dip-coated axicons remains within the measurement
    error estimation from analytical calculations. In addition to the improved surface
    finish and transparency, the coatings are also closely matched in refractive index
    to the axicon material. Such post-processed axicons pave the way for producing
    a wide array of systems in the fields of communication, imaging, and bio-sensing.

  text: "Additive manufacturing (AM), commonly known as 3D-printing, provides a cost-effective
    approach for manufacturing of prototypes. The authors illustrate material analysis
    of suitable 3D-printable materials that can be used to manufacture THz components
    and investigate and provide solutions to challenges occurring during the 3D printing
    process. Samples in this study are 3D-printed using fused filament fabrication
    (FFF) based 3D-printers Ultimaker S5 and Bambu Lab X1E.\r\nWe investigate a total
    of six materials:  High Impact Polystyrene (HIPS), High Density Polyethylene (HDPE),
    Cyclic Olefin Copolymer (TOPAS), Polypropylene (PP), Polycarbonate (PC) and Polytetrafluoroethylene
    (PTFE/ Teflon). We observed that the Teflon material contains PC as material dopant
    to reduce the melting temperature. The authors observed warping of the 3D-structure
    due to the poor adhesion of material on the print-bed. An adhesive fluid or adhesive
    sheet applied on the print-bed before 3D-printing provides proper adhesion. Air
    gaps formed between the adjacent layers during the 3D-printing results into incorrect
    evaluations. The 3D-printing setting of material flow ratio above 100% ensures
    the filling of air gaps created due to layer-by-layer manufacturing. Moreover,
    the direction of nozzle movement also helps in achieving uniformity in 3D-printed
    sample. A minimal layer height of 100 µm for the 3D-printing of all the materials
    provides promising adhesion and better finish. Some materials e.g., PP, PC, TOPAS
    capture humidity, therefore the authors used specialized chambers to maintain
    low humidity during the whole 3D-printing process. Fan speed, low surrounding
    temperature contribute in blocking of the nozzles or premature cooling of the
    samples; therefore, it is necessary to maintain the temperature during 3D-printing.
    \r\nWe investigated these samples using THz-TDS setup to find the most suitable
    material for AM of THz-components. The results reveal that the absorption coefficient
    of TOPAS is the least (α < 0.5 per cm at 0.4 THz) among all the investigated materials.
    Therefore, with the help of material analysis of 3D-printable materials for manufacturing
    of THz-components, the authors introduce fundamental research results for the
    future developments in the field of 3D-printing of THz components. \r\n\r\n[1]

  text: Additive manufacturing of optical, electrical, and mechanical components is
    a beneficial approach for the rapid prototyping of components and error elimination,
    with short turnaround times. However, additively manufactured components usually
    have rough surfaces that need post-processing, particularly for optical components,
    where the surface roughness must be a small fraction of the wavelength. We demonstrate
    an innovative and economical approach by dip-coating with the same resin used
    for printing in a simple post-processing step, providing high transparency to
    the 3D-printed optical components and reducing surface roughness while achieving
    perfect index matching of the coating layer. The surface roughness of the 3D-printed
    optical components drops to 5 nm (arithmetic average) after the dip-coating process.
    We observed significant performance enhancements after comparing the unprocessed
    optical components and the dip-coated optical components, including optical transparency
    and a shiny surface finish for previously rough surfaces.

  text: "Additive manufacturing (AM) of terahertz (THz) components is a cost-effective
    and efficient method of rapid prototyping. This work discusses the THz characterization
    of AM-compatible polymers to evaluate their potential use in the fabrication of
    THz components. The materials under investigation are primarily used in the inkjet
    3D-printing (IP) process, and are compared with other AM-compatible materials
    [1]. The authors analyzed heat resistant AR-H1 material, transparent AR-M2 material
    and flexible silicon elastomer material. After the THz time domain spectroscopy
    of these materials, it can be deduced that the materials AR-M2 and AR-H1 can be
    used in manufacturing of THz components, with the benefit of a superior printing
    resolution of 50 µm.\r\n\r\n[1] A. Shrotri, A. K. Mukherjee, S. Lohöfener, A.

  text: "Additive manufacturing of optical, electrical and mechanical components is
    a beneficial approach for rapid prototyping of components and error elimination
    with short turn around times. However, additively manufactured components usually
    have rough surfaces which need post-processing, in particular for optical components
    where the surface roughness must be a small fraction of the wavelength. We demonstrate
    an innovative and economical approach by dip-coating with the same\r\nresin as
    used for printing, providing high transparency of the 3D-printed optical components
    and reduced surface roughness with perfect index matching of the coating layer
    in a simple post processing step. The surface roughness of the 3D-printed optical
    components drops to 5 nm (arithmetic average) after the dip-coating process. We
    observed significant performance enhancement after comparing the unprocessed optical
    components and dip-coated optical components, including achieving optical transparency
    and shiny surface finish of previously rough surfaces."

  text: 'Additive manufacturing enables direct prototyping of complex 3D-objects that
    are difficult to manufacture using conventional methods. It is widely used to
    fabricate cost-efficient prototypes and portrays as a bridging technology to connect
    different scientific and industrial fields, e.g. Engineering, Medicine, etc. Consequently,
    additive manufacturing finds its applications in the production of patient-specific
    orthoses. This paper discusses the application of the stereolithography apparatus
    process to develop a pressure sensor based on an optical waveguide principle to
    embed into a below-knee orthosis. For Orthopaedic patients, the below-knee orthosis
    must be adjusted to the lower leg at regular intervals due to anthropometric changes
    in patient’s body to achieve proper mobility and correct load. Currently, this
    alteration relies on the patient’s estimation of support load and is only sub-optimal.
    Hence, the concept of developing an intelligent orthosis with a novel embedded
    optical system to monitor the exact support load at the neuralgic is proposed. '

  text: 'This paper proposes an innovative approach of manufacturing optical fibers
    using nozzle-mask-aided additive manufacturing. Nozzle-masks ease 3D-printing
    of optical fibers allowing the manufacturing or drawing of optical fibers of up
    to 10 μm diameter. These nozzle-masks feature a suction mechanism to prevent clogging
    of printhead and mask. The extrusion of Polymethyl-methacrylate material through
    the print-head and nozzle-mask simplifies the rapid prototyping of the optical
    fibers. '

  text: The ability to manufacture complex 3D-objects directly from its CAD model
    is the important reason why additive manufacturing is being widely used to fabricate
    cost-efficient prototypes and preferred over conventional manufacturing methods.
    Moreover, it portrays as a bridging technology to connect different scientific
    and industrial fields, e.g. Engineering, Medicine, etc. Consequently, additive
    manufacturing finds its applications in the production of patient-specific orthoses.
    This paper discusses the development of a pressure sensor based on an optical
    waveguide principle manufactured using stereolithography apparatus process to
    embed into a below-knee orthosis. For Orthopedic patients, the below-knee orthosis
    must be adjusted to the lower leg at regular intervals due to anthropometric changes
    in patient’s body to achieve proper mobility and correct load. Currently, this
    alteration relies on the patient’s estimation of support load which is only sub-optimal.
    Hence, the concept of developing an intelligent orthosis with a novel embedded
    optical system to monitor the exact support load at the neuralgic is proposed.

  text: Additive manufacturing provides a lucrative alternative for manufacturing
    of functional prototypes. This paper emonstrates the manufacturing and characterization
    of hollow core waveguide prototypes with circular cross section using suitable
    metal and polymers for Terahertz sensing applications. These additively manufactured
    waveguide prototypes are characterized from 0.1 to 1.25 THz to evaluate the attenuation
    and coupling losses.

  text: Additive manufacturing (AM) and rapid prototyping process (RPP) have revolutionized
    the production of 3D objects in the last few decades. RPP has considerably increased
    the rate of production and the possibility of manufacturing prototypes in the
    fields of electrical, optical, and mechanical engineering. The manufacturing of
    optical prototypes including spherical, aspheric, and special kinds of lenses
    and lens arrays has reformed the fabrication of optical components. In this paper,
    specifically designed lens array prototypes for application in visible light communication
    (VLC) are introduced. These lens array prototypes are manufactured using the stereolithography
    apparatus (SLA) process. These lens arrays are designed to achieve optimal transmission
    of the light beam for VLC systems. One of the prototypes from the lens arrays
    contains primarily four spherical lenses and one thicker convex lens and the other
    contains one fresnel lens as a substitute for thicker convex lens. These lens
    arrays are further post-processed to achieve the required transparency. These
    lens array prototypes are tested using laser and LEDs. The ON-OFF keying modulated
    light beam was transmitted through the lens array at the sender side and focused
    on the photo-receiver using another lens array at the receiver side which is 200
    cm apart. After evaluating these lens prototypes, it can be concluded that with
    appropriate post-processing and high-resolution stereolithography based manufacturing,
    a low data rate VLC link can be formed.

  text: 'Visible-light communication is a promising technology for industrial environments.
    However, a variety of physical effects may influence the communication quality
    in this potentially harsh environment: Dust and other particles lead to increased
    attenuation. Artificial light sources and industrial processes, such as grinding
    and welding, cause optical cross-talk. A multitude of reflective surfaces can
    lead to fading due to multi-path propagation. These three aspects are experimentally
    investigated in exemplary manufacturing processes at five different production
    sites in order to estimate the relative importance and their specific impact on
    VLC transmission in industrial areas. Spectral measurements demonstrate the presence
    of interfering light sources, which occupy broad parts of the visible spectrum.
    They give rise to flickering noise, which comprises a set of frequencies in the
    electrical domain. The impact of these effects on the communication is analysed
    with reference to the maximum achievable channel capacity and data rate approximation
    based on on-off keying is deduced. It is found that cross-talk by environmental
    and artificial light sources is one of the strongest effects, which influences
    the optical, but also the electrical spectrum. It is also observed that industrial
    areas differ strongly and must be categorised according to the manufacturing processes,
    which can induce quite a variation of dust and attenuation accordingly.'

  text: "Visible light communication (VLC) allows the dual use of lighting and wireless
    communication systems by\r\nmodulation of illumination devices. However, to increase
    the performance, typically, beam-forming measures are\r\ntaken creating pencil
    beams, thus contradicting the illumination purpose. In order to optimize the performance\r\ntrade
    o\v between e\x0Ecient illumination and communication, the switching capabilities
    of illumination LEDs are\r\nexamined. Illumination LEDs with standard drivers
    and without beam-forming show limited applicability for\r\ncommunication purposes
    as they are not optimized for the necessary switching capability (f \x19 11 MHz)
    and\r\ncoherence. Methods to enhance the electrical current by pre-equalisation,
    biasing, carrier sweeping and current\r\nshaping are examined in respect to the
    illumination LED's communication performance. A novel driver scheme\r\nis derived
    which achieves considerably higher switching frequencies (f \x15 100 MHz) without
    employing beamforming\r\nat the illumination LED. This driver is able to obtain
    a data rate of up to 200 Mbit/s at a distance of\r\n3.2 m, using on-o\v keying
    (OOK) modulation technique. Therefore, it is feasible to apply the LED driver
    by\r\nimplementing standardised illumination devices in VLC systems."

  text: 'In industrial scenarios wireless communication becomes more and more widespread.
    Radio-frequency technologies are still predominant, but optical wireless communication
    (OWC) provides many advantages to fulfill the requirements of communication in
    industrial applications. A survey with industrial users consolidate a list with
    the most important demands for wireless communication within the field: The results
    reveal that the current heterogeneous requirements for wireless communication
    are valid, but highlight the need for license-free, robust and energy efficient
    wireless communication at rather moderate data rates. These requirements can be
    met by OWC, but its direct application in industrial environments is often hindered
    by the harsh conditions, with measurements inter alia indicating specific cross
    talk by light-emitting processes. In this article, these aspects are discussed
    one by one in order to obtain a clear perspective about the applicability, the
    main limitations and potential technologies for OWC and competing approaches in
    industrial areas. In summary, the application requirements of industrial communication
    are substantiated, whereas specific limitations and needs for advancement of current
    OWC systems are derived.'
