Abstract

We develop a silicon photonic crystal nanocavity device capable of performing targeted optical pulse capture and release via distinct ports on demand, based on dynamic Q factor control. The capture of 4 ps pulses and their release up to 332 ps later is directly observed by time-resolved measurements of the energy behaviour in both the nanocavity and emitted from the release port. We also discuss how the behaviour of excited free carriers dictates the performance of such dynamic devices.

摘要

我们基于动态品质因数控制，开发了一种硅光子晶体纳米腔器件，该器件能够通过不同端口按需执行靶向光脉冲捕获和释放。通过对纳米腔内以及从释放端口发射的能量行为进行时间分辨测量，直接观察到了4皮秒脉冲的捕获及其在332皮秒后释放的过程。我们还讨论了受激自由载流子的行为如何决定此类动态器件的性能。
