一种不等带宽光学梳状滤波器

A Novel Interleaver with Different Output Spectrum Bandwidth

提出了一种新型—Michelson—三面镜Fabry Perot型 5 0GHz不等带宽光学梳状滤波器设计方案 ,分析和模拟表明 :该器件将一路信道间隔为 5 0GHz的输入信号分离成信道间隔为 10 0GHz的奇偶两路输出信号 ,其中在 3dB处 ,奇数信道带宽大于 30GHz用于 10Gb/s传输 ,偶数信道带宽大于 6 0GHz用于 4 0Gb/s传输 对于将来的 4 0Gb/s系统 ,该器件具有优势 .

A novel design scheme of 50 GHz unequal passband interleaving filter with two three-mirror F-P resonators is put forward based on Michelson interference. The device splitting a input beam with channel spacing of 50 GHz into two beams with channel spacing of 100 GHz, at 3 dB one of which including odd channels having more than 60 GHz passband for 40 Gb/s and the other even channels having more than 30 GHz passband for 10 Gb/s,is analysized and simulated theoretically.The filter has more advantage for 40 Gb/s systems in future.
