A novel model including the interference effect of master laser reflection is established for reflection-mode optical injection locking. This model sheds insight on the physical origin of some rather distinct but unexplained modulation characteristics of optical injection-locked vertical-cavity surface-emitting lasers (VCSELs), including data pattern inversion in on-off keying modulation, a large RF gain at low frequency, and an anomalous DC-suppression under small signal modulation, in specific locking conditions. Excellent agreement is obtained between the simulation and experiment results.
针对反射模式光注入锁定，建立了一种包含主激光反射干涉效应的新型模型。该模型揭示了光注入锁定垂直腔面发射激光器（VCSEL）一些相当独特但尚未得到解释的调制特性的物理起源，包括开关键控调制中的数据模式反转、低频下的大射频增益以及在特定锁定条件下小信号调制时的异常直流抑制。模拟结果与实验结果取得了很好的一致性。
