Extensive simulation and preliminary testing of a monolithic coplanar waveguide CPW phase shifter using an optical control technique has been performed. Improvements in numerical techniques has allowed the simulation of non-uniform lossy layers within the substrate supporting the CPW. In addition, a periodically illuminated structure has been proposed, and analysis begun on the slow wave effects expected in such a structure. A CPW transmission line has been fabricated on a AlGaAsGaAs heterostructure, and initial electrical characterization has begun.
