We report on a passively mode-locked InP/InGaAsP multiple quantum well semiconductor ring laser that operates at a 20 GHz repetition rate and around 1575 nm wavelength. The device has been realized using the active-passive integration technology in a standardized photonic integration platform. We demonstrate experimentally for the first time to our knowledge that the relative positioning of the amplifier and absorber in a monolithically integrated ring laser can be used to control the balance of power between counterpropagating fields in the mode-locked state. The directional power balance is verified to be in agreement with a model previously reported.
我们报告了一种基于 InP/InGaAsP 多量子阱半导体环形激光器的被动锁模技术，其重复频率为 20GHz，工作波长约为 1575nm。该器件采用有源-无源集成技术在标准化的光子集成平台上实现。我们首次在实验中证明，在单片集成环形激光器中，放大器和吸收器的相对位置可以用于控制锁模状态下反向传播场之间的功率平衡。所验证的定向功率平衡与之前报道的模型一致。
