Abstract: | 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 focused onto the disk resonator to turn off the resonance, thus removing coupling between two waveguides. The result shows low insertion loss of the proposed switch due to the low dissipation of the platform. The device achieves an extinction ratio of 11 dB and 1.5 GHz of terahertz bandwidth. This terahertz switch can be employed in various terahertz applications including phase shifting and beam steering. |
