Abstract:

This grant supported a MURI Fellow to work on topics in the area of Quantum Information Technology. Specifically, Jay E. Sharping worked on the following research tasks i Generation of polarization-entangled photon-pair pulses near 1.5 micron wavelength by use of the Kerr nonlinearity of standard dispersion-shifted optical fiber and ii applying the same techniques to obtain polarization-entangled photon-pair pulses near the 0.8 micron wavelength by use of novel micro-structured optical fibers also called holey fibers. In both cases, nondegenerate four-wave mixing was used to simultaneously generate signalidler photon pairs. Thorough studies of the classical nonlinear optical processes were performed and several useful applications such as parametric amplification, parametric oscillation, and all-optical switching were demonstrated. Direct detection and photon counting techniques were used to experimentally verify quantum-correlated signalidler pair production. Photon counting tools for detection at wavelengths of 1.5 micron were built and characterized. Time and polarization multiplexed four-wave mixing processes were then used to generate polarization-entangled photon pairs, and the quality of the entanglement was evaluated through quantum interference and Bell-inequality-violation measurements.
