A two-electrode semiconductor optical amplifier that has two sections and two separated electrodes is proposed for an all-optical wavelength converter. Pattern effect reduction based on dynamic gain compensation is theoretically investigated using a time-domain model that takes into account the carrier diffusion process between the two sections, and the Q factor of the converted light is calculated to evaluate pattern effects. Simulation results show that the Q factor is greatly improved when the section lengths and the currents are appropriately selected.
本文提出了一种用于全光波长转换器的双电极半导体光放大器，该放大器具有两个部分和两个分离的电极。基于动态增益补偿的模式效应降低通过时域模型进行理论研究，该模型考虑了两个部分之间的载流子扩散过程，并计算了转换光的Q因子以评估模式效应。仿真结果表明，当适当地选择部分长度和电流时，Q因子会得到极大的改善。
