Abstract
A new technique for tuning the gain of a gain-clamped erbium-doped fib re amplifier is presented. It uses a chirped fibre grating (with linea r slope reflectivity) and a narrowband uniform grating to form the las er cavity. By strain tuning the input narrowband grating, the laser fe edback is varied and the amplifier inversion and gain can be controlle d. This technique provides a continuous gain tuning capability, togeth er with clamped gain operation.
