Exploiting Optical Waveguides for Quantum Information Applications


Optical waveguides provide tight confinement of light over extended lengths which are ideal for nonlinear optical interactions.  I will describe the use of a various types of waveguides including photonics crystal fibers and silicon-based nanowaveguides for quantum information applications.  For example, we use hollow-core photonics band-gap fibers filled with Rb atoms to enable nonlinear interactions down to the few-photon level.  In addition, we can use dispersion engineering in glass and silicon nanowaveguides to produce quantum-correlated photons, frequency translation of quantum states, and photon shaping.
