Abstract

A reflective-type semiconductor optical amplifier (SOA) module has been fabricated for application both as a transmitter and a receiver in a 156 Mb/s bi-directional transmission. The low parasitic capacitance provided by the semi-insulating structure of the SOA and a bare-chip mounting technique resulted in a reduced minimum averaged received power of -34.2 dBm in receiver performance. Error-free transmission was also confirmed for a wide range of incident wavelength when the module was used as a transmitter. These results show that our module is well suited to make a cost-effective subscriber unit for a future dense WDM fiber access systems.
