Single Photons and Nonclassical Light in Waveguide Arrays

It is now recognized that arrays of classical waveguides are suitable elements for realizing a number of condensed matter optical effects like Bloch oscillations, Anderson localization, Hong-Ou-Mandel two electromagnetically induced transparency. Even PT symmetric quantum mechanics can be realized by the array. Since various interactions can be controlled by design of the array such structures are especially useful to study physical effects in a region previously unrealized. This talk would focus on some of these and quantum photon interference, entanglement, developments with special emphasis on quantum fields in such structures.
