T1 - Optically tunable entangled photon state generation in a nonlinear directional coupler T2 - CLEO: QELS_Fundamental Science 2015, San Jose, California, United States, 10-15 May 2015 N2 - We propose and experimentally demonstrate an all-optically tunable biphoton quantum light source using a nonlinear directional coupler. The source can generate high-fidelity N00N states, completely split states, and states with variable degrees of entanglement.
