摘要
提出了一种新型光学梳状滤波器 ,它由双Gires Tournois谐振腔代替Michelson干涉仪的两个全反射镜构成。基于Michelson干涉原理 ,给出了零畸变、高信道隔离度、宽平坦带宽、高一致性、结构简单、性能稳定的光学梳状滤波器的设计原理。设计了信道间隔为 5 0GHz,畸变 <0 0 5dB ,1dB带宽大于 0 38nm ,相邻信道间隔离度大于 2
A novel Interleaver using a modified Michelson interferometer in which its reflecting mirrors are replaced by two Gires-Tournois resonators is presented. On basis of the theory of Michelson interference, a designing principle of the interleaver which has square-like frequency response with zero ripple, wide flat-top, unity contrast, simple structure, and stable performance is given. The device which possesses channel spacing of 50 GHz, ripple less than 0.05 dB, 1 dB bandwidth more than 0.38 nm, and close channel isolation more than 23 dB has been designed.
