摘要
全光波长转换是全光网络的关键技术之一。利用多模半导体激光器的速率方程,建立了基于半导体激光器的全光波长转换器的理论模型,该模型不仅考虑了注入信号光对激光腔内载流子的消耗,而且考虑了激光腔对注入信号光的放大作用。利用该模型分析了半导体激光器工作电流、注入信号光功率以及码率各参数对波长转换特性的影响。结果对于确定基于半导体激光器的全光波长转换器件的最佳工作条件有一定的参考价值。
All-optical wavelength conversion is one of the key techniques of all-optical networ.A tneoretlcal modedel of alloptical wavelength converter based on semiconductor laser was established by using rate equations of multi-model semiconductor laser. Not only the carrier depletion in the laser cavity was induced by the input signal, but also the amplified effect of the laser cavity on the input signal was considered. The characteristics of wavelength conversion were analyzed in different optical parameters including the injection current, signal power and transmission rate. These results are useful to the best work condition of all-optical wavelength converter based on semiconductor laser.
