Fast-responding nonlinear phase shifter using a signal-wave gain medium

April 22, 2008

Author(s)

Lu Deng, Edward W. Hagley, Kaijun Jiang, Marvin G. Payne

Using a full density matrix formalism we show that for a lifetime broadened four-level scheme with a signal wave gain medium a large nonlinear phase shift can be induced without signal wave slowdown and attenuation. In this system the signal wave acquires

Formation and propagation of matched and coupled ultraslow optical soliton pairs in a four-level double-Lambda system

November 17, 2005

Author(s)

Lu Deng, M G. Payne, G X. Huang, Edward W. Hagley

We investigate the simultaneous formation and stable propagation of ultraslow optical soliton pairs in a lifetime broadened four-state atomic system under double- excitation with large one- and two- photon detunings. We show that detrimental probe field

Propagation Dynamics of a Temporally, Amplitude- and Group-Velocity-Matched Two-Mode Ultraslow Wave in a Three-Level Lamda System

December 22, 2004

Author(s)

Lu Deng, Marvin G. Payne, Edward W. Hagley

We investigate the propagation dynamics of a two-mode probe field traveling with ultra-slow group velocities. We show that a strong cross-beam coupling occurs between the two modes of the probe wave. In the adiabatic limit and under appropriate conditions

Ultraviolet single-photons on demand and entanglement of photons with a large frequency difference

December 20, 2004

Author(s)

Lu Deng, Edward W. Hagley, M. G. Payne, Ying Wu

We investigate an efficient scheme for generating ultraviolet single-photons s,300 nmd. The scheme combines the highly efficient single-photon four-wave mixing scheme and fast developing quantum dot singlephotons on demand source technology. We show that

Efficient multi-wave mixing in ultra slow propagation regime and the role of multi-photon quantum destructive interference,

October 1, 2004

Author(s)

Y Wu, M G. Payne, Edward W. Hagley, Lu Deng

We analyze a lifetime-broadened four-state four-wave-mixing (FWM) scheme in the ultraslow propagation regime and show that the generated FWM field can acquire the same group velocity and pulse shape as those of an ultraslow pump field. We show that a new

Preparation of multiparty entangled states using pairwise perfectly efficient single-probe photon four-wave mixing

June 3, 2004

Author(s)

Lu Deng, Marvin G. Payne, Y Wu, Edward W. Hagley

We propose a scheme to achieve multiparty entanglement with perfectly efficient, ultraslow, multichannel pairwise four-wave mixing (FWM). A cold atomic medium is illuminated with an N-mode continuous- wave (cw) control laser to produce coherent mixtures of

Synchrotron Ultraviolet Radiation Facility SURF III

March 1, 2002

Author(s)

Uwe Arp, Charles W. Clark, Alex P. Farrell, E Fein, Mitchell L. Furst, Edward W. Hagley

The National Institute of Standards and Technology (NIST) has operated the Synchrotron Ultraviolet Radiation Facility (SURF) continuously since the early 1960s. The original accelerator was converted into a storage ring, called SURF II, in 1974. Then in
