| 摘 要： | 从光电集成电路的角度出发,根据量子点半导体光放大器(QD-SOA)中载流子跃迁速率方程和光场传输方程,建立了QD-SOA等效电路模型,并通过电路仿真的方法对QD-SOA的增益谱、饱和增益特性等进行了仿真和分析;利用QD-SOA的交叉增益调制研究了速率分别为40Gbps、100Gbps和160Gbps时的波长转换特性,并分析了不同的偏置电流、功率的信号光和探测光对输出信号消光比和Q值的影响,其转换速率可达到100Gbps,消光比ER约为10dB,Q值约为2.2.该研究对提高基于QD-SOA的交叉增益调制波长转换的性能具有指导意义.

| Abstract: | From the Optoelectronic Integrated Circuits (OEIC),according to the rate equations of carriers transition and the equations of optical field propagation in Quantum Dot Semiconductor Optical Amplifiers (QD-SOA),an equivalent circuit model of QD-SOA was established.Based on the circuit simulation method,the gain spectrum and saturated gain characteristics of QD-SOA were simulated and analyzed.The characteristics of wavelength conversions at the rates of 40 Gbps,100 Gbps and 160 Gbps were studied based on the Cross Gain Modulation (XGM) of QD-SOA respectively.Meanwhile,the effect of signal light and probe light with different bias current and power on the properties of the output signal,including the extinction ratio and Q factor,was analyzed.The rate of wavelength conversions can reach 100 Gbps,Extinction Ratio(ER) is about 10 dB and Q factor is about 2.2.This study is quite important for improving the performances of wavelength conversion based on XGM of QD-SOA. |
