Abstract

We report greatly enhanced modulation response of multimode vertical-cavity surface-emitting lasers (MM-VCSELs), for the first time, using optical injection locking. A 3-dB bandwidth of 38 GHz and 54 GHz resonance frequency are achieved using a MM-VCSEL with a 3 GHz free-running bandwidth. We show that transverse mode selection can be attained with optical injection locking through frequency and spatial detuning.

摘要

我们首次报道了利用光注入锁定实现多模垂直腔面发射激光器（MM-VCSEL）调制响应的大幅增强。使用自由运行带宽为3 GHz的MM-VCSEL实现了38 GHz的3 dB带宽和54 GHz的谐振频率。我们表明，通过频率和空间失谐，利用光注入锁定可以实现横向模式选择。
