Abstract :
An optical switch made of carrier depletion directional couplers based on GaInAsP/InP double-heterostructure waveguides with integrated detectors was realised. The device was fabricated using a two step Cl-VPE epitaxy and shows good performances both in terms of switching (phase modulation efficiency approximately 12 degrees /V/mm) and detecting properties (detector leakage current approximately 1 nA at -5 V).
