Abstract

We report the successful monolithic integration of a GalnAsP/lnP single-mode AK 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 crosstalk either from the internal laser source or with external light injected through the parallel input port.
