Keywords:photonic crystal, exciton, all optical switching

We studied large Purcell enhancement [1], high-β laser with smooth lasing transition [2] and photon statics [3] using a buried multiple-quantum-well photonic crystal nanocavity. In this study, we will investigate ultra-low energy all-optical switching using exciton effect of the buried multiple-quantum-well photonic crystal nanocavity.
