大面积垂直腔面发射激光器中电激活局域结构的观察
Observation of electro-activated localized structures in broad area VCSELs
摘要:
我们在实验上证明了在低于阈值工作的相干驱动宽区域垂直腔面发射激光器(VCSEL)中局部光学结构的电激活。通过基于光折变漏斗波导的可预编程开关,通过电光操纵写入光束来实现控制。
英文摘要:
We demonstrate experimentally the electro-activation of a localized optical structure in a coherently driven broad-area vertical-cavity surface-emitting laser (VCSEL) operated below threshold. Control is achieved by electro-optically steering a writing beam through a pre-programmable switch based on a photorefractive funnel waveguide.
