Photon pair generation and pump filtering in nonlinear adiabatic waveguiding structures

Wu, Che Wen; Solntsev, Alexander S.; Sukhorukov, Andrey; Neshev, Dragomir


We propose a novel integrated scheme for generation of Bell states, which allows simultaneous spatial filtering of pump photons. It is achieved through spontaneous parametric down-conversion in the system of nonlinear adiabatically coupled waveguides. We perform detailed analytic study of photon-pair generation in coupled waveguides and reveal the optimal conditions for the generation of each particular Bell state. Furthermore, we simulate the performance of the device under realistic...[Show more]
