Dynamics of nonclassical light in integrated nonlinear waveguide arrays and generation of robust continuous-variable entanglementDynamics of nonclassical light in integrated nonlinear waveguide arrays and generation of robust continuous-variable entanglement Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-212012enWe study a class of nonlinear waveguide arrays in which the waveguides are endowed with χ(2) nonlinearity and coupled through the evanescent overlap of the guided modes. We investigate the viability of such an array as a platform for generating both bipartite and tripartite continuous-variable entanglement. We explicitly address the effect of realistic losses on the entanglement produced, discuss the possible types of nonlinear materials that could be used, and suggest solutions for the possible phase matching issues in the waveguides. The simultaneous generation and manipulation of the light on a single waveguide chip circumvents the usual bandwidth problems associated with the use of external bulky optical elements and makes this avenue promising for further investigation.http://creativecommons.org/licenses/by/4.0/Physical Review A855 Rai Amit Aggelakis Dimitrios Αγγελακης Δημητριος American Physical Society Quantum physics
