Abstract

We theoretically investigate slow and fast light propagation and pulse velocity control in a nanocavity containing a single quantum dot side-coupled to a planar-photonic-crystal waveguide. We demonstrate that low coupling strength (i.e., the weak coupling regime) between a cavity and a dot, under on-resonance condition, can lead to delays of about +90ps for a pulse 1e-width of 280ps. The group delay dependence on the various coupling parameters suggests achievable delays of +300ps and consequently very slow light speeds of around 5000ms in a 1.5μm cavity-waveguide section. We also show that under off-resonant condition one can achieve significant pulse advancement of 60ps.
