Abstract :
The dynamic characteristics of a gain saturated semiconductor laser amplifier with 1.47-μm pump light are described. In addition to improving the saturation output power, the pump light injection shortens the gain response time. Bit-error-rate measurements show that signal degradation, induced for a high-bit-rate signal amplified under the gain saturated condition, becomes less with the pump light injection.
