Abstract
We report the successful monolithic integration of a GaInasp/lnP single-mode ΔK directional coupler switch with a 4-section tunable multiple-quantum-well distributed Bragg reflector laser. We obtain several mW of output power through the switch, with ˜10dB crosstalk either from the internal laser source or with external light injected through the parallel input port.Keywords
