We show that the presence of a single photon deterministically controls the transmission of another photon. Their strong interactions are mediated by a single quantum dot spin that is strongly coupled to a nanophotonic cavity.

Single photon sources based on a self-assembled quantum dot in nanophotonic waveguides, gratings, and cavities are interfaced with nonlinear media and electro-optic modulators to demonstrate quantum frequency conversion and amplitude modulation of single photon states.

We develop a telecom-band nanophotonic spin-photon interface with erbium dopants in silicon. We perform photoluminescence spectroscopy of Er3+ in silicon-on-insulator (SOI) wafers and measure Purcell enhancement, optical linewidths and transition dipoles in nanophotonic cavities.
