A Tunable MQW-DBR Laser with a Monolithically Integrated InGaAsP/InP Directional Coupler Switch.
01 January 1989
We report the successful monolithic integration of an InGaAsP/InP single-mode DELTA kappa 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 ~10 dB cross-talk either from the internal laser source or with external light injected through the parallel input port.
