Abstract :
A gain-clamped semiconductor optical amplifier (SOA) scheme based on automatic power control of a compensating light generated from amplified spontaneous emission by a reflector is proposed. Experimental demonstrations using an SOA with a fibre Bragg grating at the input fibre show the proposed amplifier has a low noise figure as well as good gain clamping characteristics.
