Abstract

We present a compact scheme for the integrated generation of densely-spaced time-bin entangled two-photon qubits using an on-chip unbalanced interferometer and a spiral waveguide. We show quantum interference with visibilities as high as 99%.

We report the first entanglement generation experiment using an on-chip slow light device. With highly efficient spontaneous four-wave mixing enhanced by the slow light effect in a coupled resonator optical waveguide based on a silicon photonic crystal, we generated 1.5-μm-band high-dimensional time-bin entangled photon pairs. We undertook two-photon interference experiments and observed the coincidence fringes with visibilities >74%. The present result enables us to realize an on-chip entanglement source with a very small footprint, which is an essential function for quantum information processing based on integrated quantum photonics.
