Abstract
A novel single sideband electro-optic modulator includes a planar waveguide structure allowing only circularly polarized optical and microwaves to propagate therein with equal phase velocities comprises a strip loaded GaAlAs/GaAs/GaAlAs structure with appropriate microstrip electrodes. The present modulator is readily fabricated using established microelectronic fabrication techniques and a modified MOCVD epitaxial growth process.
