Abstract
We perform time-domain measurements of the interaction between light and silicon photonic crystal nanocavities under dynamic Q factor control. Time-resolved evidence of optical pulse capture and release on demand is demonstrated and compared for samples with dynamic Q ranges from ~3,000 to 26,000 and from 18,500 to 48,000. Observing the energy behaviour in response to dynamic control provides insight not available with time-integrated measurements into factors influencing device performance such as carrier absorption and pulse capture efficiency.

Summary
In order to dynamically manipulate the properties of photons, significant effort has gone into combining the precise spatial control of optical modes provided by two-dimensional (2D). The targeted capture of light in resonant modes with wavelength-order modal volumes could be applied to the slowing or stopping photons [8,9], the enhancement of lightmatter interaction [10,11] and the manipulation of strong coupling behaviour [12,13] To date, this dynamic capture has been demonstrated by spectral (i.e., time-integrated) measurements of the nanocavity emission for different relative timings of the dynamic Q factor increase relative to the arrival of the targeted light [1,7], which confirm successful light capture but are not sufficient to properly understand how the photons respond to the manipulated environment. We demonstrate the captured light can be released on demand by dynamically lowering the Q factor
