摘要：
A study is presented into the dynamic characteristics of a unidirectional regenerative erbium-doped fibre ring amplifier at below laser threshold. A considerable improvement in gain and noise figure performance was observed due to the suppression of amplified spontaneous emission in the regenerative amplification process. It was Found that lower feedback power provides higher optical gain. An optical signal of -33.5dB was found to experience a gain of greater than or equal to 35dB at and near the resonance wavelength using 1% feedback by an optical fibre coupler for an optical pump (1480nm) power as low as 10mW.
