资料介绍

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QI)_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QnSOA的交叉增益调制波长转换的性能具有指导意义.

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...
