The monolithic integration of a semiconductor laser optical preamplifier and an edge-coupled PIN photodiode has been demonstrated for the first time. Although the fabrication involved is relatively simple, a maximum gain (excluding input coupling loss) of 20 dB and a 3 dB bandwidth of 35 GHz has been measured for this device.
