Abstract :
We demonstrate a single-pole single-throw switch in W-band based on the optical illumination of a defect waveguide in a photonic crystal. Simulations show that an extinction ratio of greater than 40 dB between 89 and 101 GHz is possible. Measurements at 99 GHz confirm this extinction ratio.
