Abstract

We investigate utilizing nonlinear metamaterials for generating entangled photons with expected characteristics. Metamaterials are artificial structures with unique properties which are not attainable with naturally existing materials. In recent years, owing to high designability and flexibility, metamaterials have been deeply investigated and utilized for constructing novel photonic devices. Through tailoring the nanostructures of metamaterials with feasible nonlinear optical character, we can control the PDC process inside the medium to generate desirable photon states. Various spatial perturbations of optical parameters with special distributions can be introduced in via suitable arraying of elements of metamaterials. The spatial properties of entangled photons such as orbital angular momentum can be flexibly engineered. The nonlinear metamaterial provides a flexible platform for steering photonic entanglement.
