Terahertz frequency regime waveguide photonic microstructures for electro-optic modulation

Applies photonic bandgap and microcavity concepts in multifunction devices in which the local periodicity of the structure determines whether it is a low-loss mirror stack for a terahertz microcavity or (potentially) an electrooptic beam-steering antenna. Periodic structures of the same type, but with an increased period length, become receiving/transmitting antennae. It will also be useful to consider other electrooptic materials, in particular the III-V semiconductors, and thus identify alternative materials which combine strong electrooptic effects with low absorption losses at terahertz frequencies
