InP photonic integrated circuit for BOTDR fiber sensing

We realized a potentially low-cost optical fiber sensor read-out unit. The device allows for a measurement distance resolution of about 2 m along a sensing fiber using 25 ns wide pulses generated on chip. © OSA 2013.

Hybrid InP-SiGe photoreceiver for the access network

In this paper, we present a low cost and polarization independent photoreceiver which is part of the optical network unit (ONU) for the fiber access network. It consists of one InPphotodetector and a low cost SiGe amplifier. It operates error free with 223 − 1 PRBS word length at 1.25 Gbit/s with -13dBm input optical power before the fiber chip...
