Abstract

Photonic crystal (PC) cavities formed in a thin semiconductor slab¹ can confine light at the nanoscale with unprecedented ability. Because of the extremely strong light-matter interaction in these structures, much attention has focused on exploring solid-state cavity- QED in PC cavities containing semiconductor quantum dots (QDs). Many basic quantum information functions can be realized in these combined QD/cavity devices, and recent experiments have demonstrated preliminary cavity-QED effects between a single QD coupled to a high quality factor (Q) PC nanocavity mode.^2-4 However, progress in this field is severely hindered by the inability to precisely control the position of the QD in the cavity and the resonant wavelengths of the nanocavity modes.
