摘要
提出一种基于全光纤有源环形腔结构的双可调谐窄带滤波器。它能够充分利用腔中掺铒光纤放大器(EDFA)的宽带增益特性，有效可调谐滤波范围达到39nm，并改善了腔精细度对EDFA增益非平坦度的相关性。通过改变抽运功率，可方便地对其精细度进行调谐，从而实现全光纤结构滤波器的滤波波长和精细度的双可调谐。
Abstract
In this paper, a kind of dual tunable narrow bandpass filter is proposed based on the structure of all optical active fiber ring resonator. The tunable bandpass filter′s wavelength tuning range is 39 nm, from 1526 nm to 1565 nm. By changing the power of pump LD, its finesse can also be tuned.
