Abstract:
A sub-terahertz vortex dielectric waveguide was designed and fabricated in the cyclic olefin copolymer (TOPAS) compound. The annular index profile was engineered using a holey cladding to support operation from approximately 200-300 GHz. The vortex waveguide was tested at 280 GHz using an OAM-endowed Laguerre-Gaussian mode generated by a stepped spiral phase plate.
