【摘要】 提出了一种简单实用的粗波分复用(CWDM)器件,这种器件级联8个多层介质膜滤波器,以解复用出波长间隔为20nm的8路光信号,两个由8个自聚焦透镜和8根光纤组成的阵列对置于这些多层介质膜滤波器后,以接收8路解复用后的光信号。测试结果表明,该器件各种性能均较好。更多还原

【Abstract】 A simple and practical CWDM device was proposed, 8 multilayer thin-film-filters were placed in series to demultiplex 8 channel 20 nm spaced optical signals, behind these multilayer thin-film-filters there were 8 GRIN lenses and 8 fibers were arranged in two array-pairs to receive those demultiplexed signals。Test results showed that the performances of our device were satisfactory.更多还原
