Record Gain x Bandwidth (6.1 THz) Monolithically Integrated SOA-UTC Photoreceiver for 100 Gbit/s Applications
01 January 2014
We present a pre-amplified high-speed photoreceiver comprising a uni-traveling 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 (PDL) of 1-2 dB and 95 A/W peak responsivity corresponding to record gain-bandwidth product of 6.1 THz.
