In this paper, a kind of dual tunable narrow bandpass filter is proposed based on the structure of all optical activefiber ring resonator.
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。
2
Because there is gain material in the resonator, the activefiber ring resonators show polymorphic characteristics in their different working state.
有源光纤环形腔,由于在腔中含有增益介质,所以其工作特性具有多态性。

Based on this formula, the effects of the linewidth of input laser and the parameters of an activefiber ring resonator on the output linewidth were discussed.
