Abstract
A novel single sideband electro-optic modulator is characterized by a reentrant waveguide structure. The reentrant waveguide structure allows for a factor of four enhancement of conversion efficiency and a factor of five reduction in phase velocity mismatch between the optical wave and modulating microwave due to microwave dispersion in wideband (2 GHz) operation.
