We have demonstrated classical and quantum information processing devices enabled by strong light-matter interaction in photonic crystals, including quantum dot-photonic crystal single photon source, ultrafast photonic crystal nanocavity laser, and small quantum network on chip.

We propose a system for scalable on-chip optical QIP using a coupled atom-cavity system in a silicon photonic crystal slab. Device design is optimised using plane wave expansion (PWE) and finite difference time domain (FDTD) simulations, and devices are presented which allow non-intrusive experimental characterisation before and after ion implantation.

The experiments show that the coupled QD-cavity system is a promising candidate for probing CQED as well as for optical information processing. Our present work includes building of a three level system in a QD coupled to cavity, which is essential for construction of any quantum information processing devices.
