声光可调谐滤波器(AOTF)之模分离器的研究及设计
Research and design of mode splitter in AOTF
摘要
Abstract
The modules of optical waveguide, surface acoustic waveguide and mode splitter, and the parameter design of interdigi-tal transducer are most important in the design of acousto-optical tunable filter (AOTF). The phase difference between symmetrical mode and asymmetric mode in the mode-splitter was calculated with BPM method. The design results that TE mode has 100% conversion efficiency, and the relation curve of coupling length and forficate angle (while the conversion efficiency of TM mode is zero) were obtained. From the curve, and which satisfy the condition of TE mode and TM mode simultaniously can be obtained. The performance analysis of the mode-splitter designed in this way was carried out by the aid of BPM.关键词
