Abstract
We report the first demonstration of broadly electrically tunable (215 Å), narrow-band (∼20 Å full width at half maximum), wavelength selective, grating-assisted coupling between vertically stacked buried rib InGaAsP/InP channel waveguides. This current injection tuned device is suitable for integration in a variety of photonic devices and integrated circuits including broadly tunable extended cavity lasers, amplifier/filter, and demultiplexer/detector circuits.Keywords
