A low-loss small-sized demultiplexer using a diffraction grating in the Littrow mounting is realized for a wavelength division multiplexing (WDM) system for optical fiber systems. The system has five channels and a wavelength spacing of 200 A in the 0.8-microm region. Insertion loss was about 1.7 dB in each channel, and cross talk was <-30 dB. These characteristics make this demultiplexer the most suitable device available for optical fiber systems employing WDM configurations.
一种采用利特罗装置中的衍射光栅的低损耗小型解复用器，被应用于光纤系统的波分复用（WDM）系统中。该系统有五个通道，在0.8微米区域内波长间隔为200埃。每个通道的插入损耗约为1.7分贝，串扰小于-30分贝。这些特性使这种解复用器成为采用WDM配置的光纤系统中最合适的可用器件。
