- Single-photon routers are an essential component of integrated photonic circuits. This work presents the first demonstration of just such a voltage-controlled on-chip router, using emission from a single InAs quantum dot in a photonic crystal cavity. Experimental evidence reveals that two routing mechanisms are fundamentally needed: resonant coupling to one of two cavity modes when the emission is Stark-tuned into resonance with the mode and preferential coupling of the modes to two waveguides incorporated into the cavity at different angles. This work provides the pathway to scalable, low-power, high-speed operation of integrated photonic circuits to enable quantum computing.
