摘　　要：密集波分复用(DWDM)是光纤通信增容的首选方案,而波分复用/解复用器件(DWDM器件)是DWDM系统中的关键器件。本文讨论了DWDM器件的几种典型制作方法,其中薄膜滤光片(TFF)型器件是最富竞争力的,并对TFF 型DWDM器件的制作工艺、主要特性参数及其测试方法开展了实验研究,对我们自行研制的四通道TFF型DWDM器件的测试结果表明:该器件具有精确的中心波长、宽且平坦的带通、小而均匀的插入损耗以及较大的信道隔离度等特性,具有很好的应用前景。Dense wavelength division multiplexing (DW DM ) is the preferred technology for expanding capacity in optical fiber communicat ion, and the wavelength division multi/demultiplexers (DWDM device) is the core components in DWDM systems. In this paper, the typical fabrication schemes of DW DM device are discussed, and the thin film filter (TFF) DWDM device is very riva lrous. The experimental research is developed on the fabrication process, primar y characteristic parameters and corresponding testing means of the TFF DWDM devi ce. The testing results of a four channel TFF DWDM device which is fabricated in our lab indicate that the device has accurate central wavelength, wide and flat Channel pass-band, less and even Channel inserting loss and large channel isola tion Characteristics etc. The applications foreground is very wide.
