A Microstructure Fiber Two Photon Source With Conjugate Laser Pumps

August 25, 2005
Author(s)
Jingyun Fan, Alan L. Migdall, L Wang
We present a systematic experimental study of generating correlated photon pairs using a reversed degenerate four-wave mixing process. By overlapping a pair of parallel- (or cross-) polarized laser pump pulses at conjugate frequencies in a microstructure

Efficiently Generation of Correlated Photon Pairs in Microstructure Fibers

May 22, 2005
Author(s)
Jingyun Fan, Alan L. Migdall, L Wang
We report the efficient generation of correlated photon pairs by four-wave mixing in a 1.8 meter long microstructure fiber. The detected coincidence rate is 10,000/s with 0.8 nm collection bandwidth, the highest to date in a fiber-based photon source. The

Photonic Technologies for Quantum Information Processing

October 2, 2004
Author(s)
Prem Kumar, P G. Kwiat, Alan L. Migdall, Sae Woo Nam, Jelena Vuckovic, F Wong
The last several years have seen tremendous research toward practical optical quantum information processing, including single- and entangled-photon sources and high-efficiency photon counting detectors, covering a range of wavelengths. We review some of

Coupling Efficiencies in Single-Photon On-Demand Sources

February 1, 2004
Author(s)
Stefania Castelletto, Ivo P. Degiovanni, M J. Ware, Alan L. Migdall
Many quantum computation and communication schemes require, or would significantly benefit from, true sources of single photon on-demand (SPOD). Unfortunately, such sources do not exist. It is becoming increasingly clear that coupling photons out of a SPOD

Status of a Multiplexed Single Photon On-Demand Source

August 1, 2003
Author(s)
Alan L. Migdall, Stefania Castelletto, M J. Ware
We present the status of our work implementing a single photon on-demand source based on a multiplexed arrangement of parametricdownconverters. An array of downconverters with multiplexed outputs makes it possible to create light pulses with increased
