Abstract

We present a novel approach for all-optically reconfigurable integrated generation of quantum entangled photons in cluster states through spontaneous parametric down-conversion in coupled arrays of quadratic nonlinear waveguides with special poling patterns.

Generation of reconfigurable photon-pair states in aperiodically poled quadratic waveguide arrays

James Titchener, Alexander S. Solntsev, Andrey A. Sukhorukov

We propose special poling of quadratic nonlinear waveguide arrays enabling generation of photon pairs in any path entangled quantum state. Real-time switching between output quantum states can be achieved by varying classical input laser amplitudes.

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

James Titchener, Alexander S. Solntsev, Andrey A. Sukhorukov

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 susceptibility and accordingly shapes the interference of biphoton quantum states generated along the waveguides. We demonstrate a device configuration for the generation of any linear combination of two-photon Bell states.
