Integrated disk resonator on substrateless dielectric waveguide platform for terahertz switch applications

, 2022
We present a terahertz single-pole double-throw (SPDT) switch based on an integrated disk resonator for a substrateless dielectric platform made of an all-silicon-based effective medium. The switch operates based on photoexcitation by using visible light
