波分复用传输技术是今后光纤传输系统的主要发展方向之一。近年来,光栅分波器的研制工作进展很快,各种类型的光栅分波器不断出现。在理论工作方面则多集中于研究理想情况下光栅分波器的设计法,但是在实际情况中,光栅分波器总是非理想的,尤其是透镜的球差,对光栅分波器的传输特性影响很大。鉴于这种情况,本文重点研究了在透镜存在球差的非理想情况下光栅分波器的分析与设计方法。
Wavelength division multiplexing transmission technology is one of the main development directions of the optical fiber transmission system in the future. In recent years, the development of the grating splitter has progressed rapidly, various types of grating splitters continue to appear. In the theoretical work, the focus is more on the design method of the grating splitter under ideal conditions. However, in practice, the grating splitter is always not ideal, especially the spherical aberration of the lens, the transmission characteristics of the grating splitter great influence. In view of this situation, this dissertation focuses on the analysis and design of grating splitters in the case of non-ideal lens with spherical aberration.
