Abstract

Surface Acoustic Waves (SAW) are employed to deliberately modify the resonator properties of a high Q photonic crystal membrane (PCM) on a semiconductor nano structure. The SAW periodically deforms the PCM, giving rise to a periodically modulated resonance position of the photonic crystal. While achieving resonance shifts exceeding Δλ = 2 nm, the quality factor of the PCM resonance remains basically unchanged. Combination of the acousto-photonic resonance modulation with single photon generation of acoustically charged quantum dots and quantum posts are discussed in the context of single photon generation of non-classical light.
