  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: 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.
