摘　　要：提出利用无源耦合腔结构以拓展VCSOA的增益带宽,从而实现基于VCSOA的交叉增益调制波长转换新构想。结合载流子密度速率方程和传输矩阵方法,首次对该新型耦合腔结构VCSOA的波长转换特性进行了数值模拟,重点研究了泵浦光功率以及信号光功率对转换光消光比特性的影响。仿真获得了上下各4nm的波长转换范围,该结果已大大高于普通单腔结构VCSOA的增益带宽。In order to realize the wavelength conversion based on the Vertical-cavity Semiconductor Optical Amplifiers （VCSOAs）, the coupled cavity structure was designed to broaden the bandwidth of VCSOAs. Combined the carrier density rate equation with the transfers matrix, the wavelength conversion of VCSOAs was simulated numerically based on the cross-gain modulation for the first time. The conversion bandwidth of 4nm was obtained and the influence on the extinction ratio characteristic by the pump power and signal power was also discussed.
