We report the monolithic fabrication of a stop-cleaved laser with a monitoring detector. Stop-cleaved, double channel planar buried heterostructure lasers with threshold currents of 57 mA have been obtained emitting at 1.3-μm wavelength. For the monitoring detector on the same substrate we have estimated a quantum efficiency of 31% from the measured responsivity of 14.4 μA/mW and the theoretical diffraction coupling efficiency.
