Optics Control Microwaves. The Next Step

Paper i proceeding, 1990

A brief review of optical interactions in semiconductors from the point of view of optical control microwave device is given. Problems of optimization of microwave devices on semiconductor substrate (to meet the optical control) are discussed. The use of integrated optic (IO) thin film waveguides and devices as "optical bias" circuits opens a way for complete integration of optical control microwave devices on a single substrate and for essential reduction of control power consumption. Experimental devices - integrated optical fed gap in microstrip and asymmetric coplanar waveguide attenuator/modulator on silicon substrate are studied
