A 35 GHz photodetector with gain

Describes an edge-coupled p-i-n photodiode that is monolithically integrated with a 1.5 mu m optical preamplifier. This device not only compensates for coupling loss, but also provides net gain. The frequency response of two devices of photodiode lengths of 35 mu m and 75 mu m were measured. The bandwidth measured were 15 and 35 GHz, and the gain were 10 dB and 6 dB respectively.<
