摘要
研究了法布里 -珀罗 (F -P)型级联可调谐光滤波器在密集波分复用系统中引入的信道间串扰对系统的影响 ,并分别讨论激光线宽、光波导损耗、信道间距对串扰的影响。对设计的器件 ,在信道间隔为 2 5GHz,激光线宽为 5GHz时 ,串扰可达
Crosstalk to the tunable F-P filter with cascaded in DWDM systems is investigated.The influence of LD linewidth and the propagation loss of optical waveguide and the channel spacing on the crosstalk are analyzed,and the crosstalk is to -17 dB when the LD linewidth and the channel spacing are 5 GHz and 25 GHz,respectively.
