High-performance semiconductor optical preamplifier receiver at 10 Gb/s

摘要

A semiconductor optical preamplifier receiver for bitrates of 10 Gb/s is described. The measured sensitivity is -28 dBm, with a polarization sensitivity of less than 0.5 dB. Using the same transmitter and receiver configuration but with a 980-nm pumped fiber amplifier instead of the semiconductor amplifier, the sensitivity is -34 dBm
