Research Of The Integrated WDM Demultiplexing Photo Dectors

The research work included in this thesis was supported by grants from National Basic Research Program of China, "Basic Research on Integrated Optoelectronic Devices and Microstructure Optical Fibers with Structure and Technology Innovations for Future Advanced Optical Communications" (2003CB314900).Recently,the increasing demand for bandwidth of telecommunication has greatly promoted the development of optical fiber communications. One of the promising technologies is wavelength-division multiplex (WDM) that has been developed rapidly in the long haul communications, and the all-optical network based on WDM just under intensively research. Photo detecting of wavelength demutiplexing has become the key technology of WDM applications. In this paper, we have studied the WDM/DWDM demultiplexing detectors and got some achievements.The main research work is listed below:1. Gaved a description of the influence of unparallel F-P cavity to theresonance of the cavity.2. Conceived the structure of the integrated WDM demultiplexing photodetectors3. Participated in the experiment of the vertical taper structures factureand produced various vertical taper structures in the extension layer of...
