Abstract :
We present a systematic investigation of the poling-induced electrooptic (EO) effect in germanium and nitrogen codoped channel waveguides. The channel waveguides show attractive properties: (1) almost polarization independent EO effect; (2) a flat frequency response with the modulation frequency up to 100 kHz; and (3) low linear loss and low polarization dependent loss, which demonstrate great technological potential.
