摘要

Optical superlattices (Nonlinear Photonics) have been successfully applied to laser frequency conversion and nonlinear optics. In this talk, I will introduce the recent progress on the study of optical superlattices in quantum optics in our lab. The novel entangled two-photon pairs with unique time-frequency and space-momentum properties have been produced from the optical superlattices with the predesigned domain structures by quasi-phase-matched spontaneous parametric down-conversion. The progress exhibits the exciting perspectives of optical superlattices in exploring basic quantum mechanical effects and developing novel quantum devices.
