| Research Abstract |
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.
