10 GHz optical receiver using a travelling-wave semiconductor laser preamplifier

A 1.5 μm optical receiver with a bandwidth of 10 GHz has been demonstrated. The receiver used a travelling-wave semiconductor laser preamplifier and had an equivalent input noise of 1 pA/√Hz) with a 3 dB bandwidth of 10 GHz. The estimated sensitivity at 15 Gbit/s was −27 dBm.
