We report on a monolithic adjustable gain clamped semiconductor optical amplifier (AGC-SOA). The device consists of 2 tuneable gratings and a gain section and enables the gain of the SOA to be regulated without loss of saturated output power. Gain control is achieved by adjusting the wavelength overlap of two Distributed Bragg Reflector gratings positioned at either side of the active region which...
The presentation will describe the design and performance of an adjustable gain-clamped semiconductor optical amplifier (AGC-SOA) designed to maximize the output saturated power while adjusting gain across a wide dynamic range. This device is shown to modulate gain at rates that are compatible with packet to packet equalisation.
The growth in demand for high bandwidth services has stimulated the deployment of Passive Optical Networks (PONs), directly to the home or to the kerb. In many cases, particularly extended reach PONs which may cover distances of 100 km or more <citerefgrp><citeref refid="ref1"/></citerefgrp>, there is the need for low cost reach extension technologies. Semiconductor Optical...
A theoretical model for an adjustable gain-clamped semiconductor optical amplifier (AGC-SOA) has been established, based on the wideband steady-state numerical model of SOA. The preliminary simulation characterization results agree well with experimental data.
