New Functions of VCSEL Photonics

对VCSEL相关器件的新功能提出了挑战，包括基于VCSEL结构的波长控制和光学相位控制。利用一种新型的热驱动薄膜反射镜实现了微机械VCSEL的无热工作。我们提出了一种基于VCSEL可饱和吸收体的光学非线性移相器。在建模和实验中都可以观察到很大的非线性相移。提出的器件用于减轻光纤非线性在光域。此外，VCSEL中常用的高反射周期镜使我们能够以慢光效应操纵光。这种新的方案为我们提供了超小型的强度调制器、光开关等。

Challenges for new functions of VCSEL-related devices have been carried out, which include the wavelength control and optical phase-control based on VCSEL structures. The athermal operation of micromachined VCSELs was demonstrated with a novel thermally-actuated membrane mirror. We demonstrated an optical nonlinear phase shifter based on a VCSEL saturable absorber. A large nonlinear phase shift could be observed in both modeling and experiments. The proposed device was used for mitigating fiber nonlinearities in optical domain. Also, highly reflective periodic mirrors commonly used in VCSELs enabled us to manipulate light with a slow light effect. This new scheme provided us ultra-compact intensity modulators, optical switches and so on.
