Abstract

We present a preamplified high-speed photoreceiver comprising a unitraveling carrier photodiode (UTC) monolithically integrated with a semiconductor optical amplifier (SOA). The SOA-UTC photoreceiver exhibits above 95-GHz 3-dB bandwidth, 8-dB noise figure, low polarization dependence loss of 1–2 dB and 95-A/W peak responsivity corresponding to record gain-bandwidth product of 6.1 THz.
