Abstract
The characteristics of an optical waveguide phase shifter using free-carrier depletion in a reverse-biased double-heterostructure p-n junction are given for the first time. Ridge waveguides were fabricated by liquid-phase epitaxy and wet chemical etching in AlGaAs/GaAs. The largest phase-shifting efficiency (54°/V mm) ever reported in a reverse-biased structure was observed.
