Abstract

Optically controlled wave propagation effects in coplanar transmission lines on semiconducting substrate are reviewed in this paper. In particular, distributed Schottky photodiodes are examined where a depletion layer is formed below the center conductor. Experimentally, phase shifts as high as 110 deg/mm at 9 GHz using an optical power of merely 50 μW are obtained for an optimized InAlAs-InGaAs-InP heterostructure
