通过动态调谐超高q光子晶体纳米腔，证明了绝热频移现象。通过对输出的时间和光谱分析，我们发现光在腔内的频率遵循腔共振位移，并在整个过程中保持单模态。这明确地证实了频移是由绝热调谐引起的。我们利用这一过程实现了超高q腔中捕获光的动态释放，从而产生短脉冲。这种方法提供了一种动态调优Q的简单方法。
Adiabatic frequency shifting is demonstrated by tuning an ultrahigh-Q photonic crystal nanocavity dynamically. By resolving the output temporally and spectrally, we showed that the frequency of the light in the cavity follows the cavity resonance shift and remains in a single mode throughout the process. This confirmed unambiguously that the frequency shift results from the adiabatic tuning. We have employed this process to achieve the dynamic release of a trapped light from an ultrahigh-Q cavity and thus generate a short pulse. This approach provides a simple way of tuning Q dynamically.
