摘要
实现全光波长转换主要利用四种非线性效应 :交叉增益调制 (XGM)、交叉相位调制 (XPM)、四波混频 (FWM)和差频 (DFG)效应。根据所用非线性器件不同 ,分别介绍了基于这四种效应的全光波长转换器的基本原理、系统结构、特点和发展现状。每种波长转换器都有其不足之处 ,针对这一现实 ,重点介绍了国内外最新的全光波长转换方案 ,这些方案在一定程度上改进了原有波长转换器的性能 ,促进了全光波长转换器的实用化进程。
All-optical wavelength conversion (AOWC) is mainly implemented by using four nonlinear effects: cross gain modulation (XGM), cross phase modulation (XPM), four wave mixing (FWM), and difference frequency generation (DFG). According to the different nonlinear devices used the principles, structure, characteristics and development of all-optical wavelength converters based on the four nonlinear effects are respectively presented. Each of them has their own disadvantages, so new AOWC schemes at home and abroad are introduced in detail, which improve the performance of AOWC and accelerate its commercialization progress.
