We propose and demonstrate the digital resonance tuning of high-Q/Vm silicon photonic crystal nanocavities using self-limiting atomic layer deposition. Control of resonances of 122 plusmn 18 pm per hafnium oxide atomic layer is achieved.
A pulse delay corresponding to a slow group velocity of ~0.008 c was observed in a low-loss coupled cavity waveguide formed by 60 photonic crystal nanocavities whose intrinsic Q was as high as 106.
A new photonic crystal nanocavity combined with built-in air slots achieved an experimental Q of over 106 even when the photonic crystals on either side of the line defect had only a few lateral periods.
We demonstrate catching and releasing of optical pulses by dynamic Q factor control of a photonic crystal nanocavity. Optical pulses are caught and released on demand within the photon lifetime.
We design photonic crystal microcavities in diamond films for applications in quantum information yielding high quality factors Q>66000 and small mode volume Vap1.1(lambda/n)3. The calculated quality factors show a strong dependence on material absorption.
