Abstract :
A high-speed differential photoreceiver module for the photonic asynchronous transfer mode (ATM) packet switching system has been developed. This module employs a hybrid integration of a planar lightwave circuit (PLC) platform and a waveguide dual p-i-n photodiode. The PLC platform offered the optical signal processing functions of a tunable coupler and a half-bit delay line to handle Manchester-encoded optical signals. The flip-chip bonding of a dual p-i-n photodiode using AuSn solder bumps and a low-loss microstrip line enabled a very wide bandwidth larger than 20 GHz. This module successfully received 12-Gb/s Manchester-encoded optical signals. The module can be used in the broadcast-and-select photonic ATM switching nodes.
