摘　　要：为了易于实现解复用波长数目和间隔上的升级,设计了一种新型16波长/100GHz间隔密集波分解复用器。该器件由100GHz光梳状滤波器和200GHz介质膜滤波器构成:利用光梳状滤波器的并行输出来扩展解复用信道之间的间隔,通过介质膜滤波器的串联来实现不同波长的解复用。实验研究表明,该器件具有良好的性能,能够满足系统升级的需要。A novel type of 16-channel, 100GHz spaced dense wavelength division demultiplexer, composed of 100GHz optical interleaver and 200GHz dielectric filters is presented,which can easily meet the demand that the amount of demultiplexed wavelengths gets larger and the spacing of them gets narrower. An optical interleaver is used to enlarge the spacing of demultiplexed channels,and several 200GHz dielectric filters are cascaded on the output of interleaver to separate the different wavdengths. The experimental results show that this device has excellent performances and suits the upgrade of dense wavelength division multiplex（DWDM） systems.
