【摘要】 波分复用技术是解决宽带，大容量光纤通信网络的一种有效方法，波分复用／解复用器件是WDM系统的关键器件。基于平面光波回路PLC的阵列波导光栅AWG器件可以实现高性能，多通道，高波长分辩率的波分复用／解复用。 本文以设计阵列波导光栅器件为目标，对介质波导光场的本征波函数，光波导本征模理论，光波导衍射场特性，光波导模式耦合理论和AWG器件的光谱响应特性及模拟方法进行了深入研究，建立了一套基于本征模式场分析的光波导光束传输理论，为波导器件的设计提供正确的理论基础，并尝试了利用多孔硅生长厚的二氧化硅，用于制作波导包层材料。更多还原

【Abstract】 Wavelength Devision Multiplexing （WDM） has become the technology to meet the rapid increase of bandwidth and capacity requirements in communication systems and networks, Multiplexing and De-Multiplexing devices are the key components in WDM system. Arrayed waveguide grating is one of those components which is based on PLC technology.Aim at designing arrayed waveguide grating for WDM system., The paper is concerned with the eigen functions of optical fields in dielectrics, the theories of optical waveguide eigen mode, the characteristics of optical waveguides diffracted field, the theories of mode coupling in optical waveguides and the spectral response theories and simulating method for arrayed waveguide grating. In this paper, a set of beam propagation theory based on eigen modes analysis is set up which afforded theoretical basis for designing and analyzing AWG devices. Experiment of fabricating SiO₂ layer by using porus silicon is also carried out in this paper, which is a new method for fabricating waveguide cladding layer.更多还原
