Generation of photons with all-optically-reconfigurable entanglement in integrated nonlinear waveguides

Titchener, James; Solntsev, Alexander; Sukhorukov, Andrey


We predict that all-optically-reconfigurable generation of photon pairs with tailored spatial entanglement can be realized via spontaneous parametric down conversion in integrated nonlinear coupled waveguides. The required elements of the output quantum wave function are directly mapped from the amplitudes and phases of the classical laser pump inputs in each waveguide. This is achieved through special nonuniform domain poling, which locally inverts the sign of quadratic nonlinear...[Show more]
