Abstract

We demonstrate an InP-based photodetector with a monolithically integrated SOA. The device allows the detection of signals with 14dB less optical input power, without using electrical amplification. Due to the short carrier lifetime in the SOA, amplification without pattern effects for signals with a symbol rate of 56GBd is achieved.
