Monolithic Phase Shifter Study.

Abstract

Modeling and preliminary testing of a monolithic coplanar waveguide (CPW) phase shifter using both optical and Schottky-contact control techniques has been performed. Simulation work on a periodically illuminated structure has been completed, showing that some improvement in performance may be possible, although with a reduction in frequency bandwidth. CPW transmission lines have been fabricated on semi-insulating GaAs, on heavily doped epi GaAs, and on an A1GaAs/GaAs heterostructure, and initial electrical characterization has been performed. Optically controlled phase shift has been obtained with the heterostructure device, and Schottky-bias controlled behavior has been seen with the epi sample.
