摘要
波分复用技术是当今光纤通信系统中的关键技术之一。具有增加光纤通信系统容量的巨大潜力，集成光学复用技术对于单模光纤通信系统特别重要本文给出了一种集成光学复用器件的设计和制作，这种集成光学滤波器是在之切ＬｉＮｂＯ３衬底上用非对称钛扩散条波导定向耦合器构成，它适于１．３２μｍ和１．５５μｍ波长耦合滤波。为了使单模光纤和条波导有效耦合，我们研制出了硅Ｖ型槽，并给出了一种光纤与波导的连接结构。提供了一种切实可行的途径。
Wavelengthdivision-multiplexing technology is now recognized as one of thekey techn ologies in op tical fiber communication systems, Because it has great potentialbo enhance the capacity of the optical fiber communication systems, The Integratedoptical wavelength-division-multi/demultiplexing is also an imp ortant technique for single-mode fiber communication Sy stems. In this paper, the design, fabrication of a tunableoptical filter composed of coupled nonidential Ti-diffused strip waveguides on a Z-CutLiNbO3 substrate for λ=1. 32μm and λ=1. 55μm is fabricated. We have fabricated the V-groove structures on silic on for connecting fibers to waveguides. We also report on aconnetor strcture of fibers in silicon V-groove to waveguides,
