Demonstrated are 1060 nm microelectromechanical-systems-based tunable vertical-cavity surface-emitting lasers (MEMS-VCSELs) with a 100 nm continuous tuning range under repetitively scanned operation at rates beyond 500 kHz and a 90 nm continuous tuning range under static operation. These devices employ a thin strained InGaAs multiple quantum well active region integrated with a fully oxidised GaAs/AlO bottom mirror and a suspended dielectric top mirror. The devices are optically pumped via 850 nm light. These ultra-widely tunable lasers represent the first MEMS-VCSELs reported in this wavelength range, and are ideally suited for application in ophthalmic swept-source optical coherence tomography.
展示了基于微机电系统的1060纳米可调谐垂直腔面发射激光器（MEMS-VCSEL），在超过500 kHz的重复扫描操作下具有100纳米的连续调谐范围，在静态操作下具有90纳米的连续调谐范围。这些器件采用了薄应变InGaAs多量子阱有源区，集成了完全氧化的GaAs/AlO底部反射镜和悬浮介电顶部反射镜。这些器件通过850纳米光进行光泵浦。这些超宽可调谐激光器是该波长范围内报道的首批MEMS-VCSEL，非常适合应用于眼科扫频光学相干断层扫描。
