Dual-channel, single-photon upconversion detector at 1.3 mm

August 3, 2012
Author(s)
Jason S. Pelc, Paulina Kuo, Oliver T. Slattery, Lijun Ma, Xiao Tang, Martin M. Fejer
We demonstrate efficient, single-photon upconversion detection of two wavelengths in the 1300-nm band. The upconversion detector is based on a phase-modulated, periodically poled LiNbO3 waveguide that simultaneously quasi-phasematches two sum-frequency

Dual-channel, single-photon upconversion detector at 1300 nm

Paulina Kuo, Jason S. Pelc, Oliver T. Slattery, Lijun Ma, Martin M. Fejer, Xiao Tang
We show a dual-channel, upconversion detector at 1.3-m-wavelength based on phasemodulated periodically poled LiNbO3, and use it for wavelength- to time-division multiplexing to achieve high data rates, useful for quantum key distribution.

Single Photon Detection Using Frequency Up-conversion with Pulse Pumping

September 1, 2011
Author(s)
Lijun Ma, Oliver T. Slattery, Xiao Tang
This chapter delivers a general overview of the theoretical and experimental results of single photon up-conversion detectors with pulse pumping. After a brief introduction, we provide a detailed coverage of several key applications of up-conversion

Temporal Correlation of Photons Following Frequency Up-conversion

May 23, 2011
Author(s)
Lijun Ma, Matthew T. Rakher, Martin Stevens, Oliver T. Slattery, Kartik Srinivasan, Xiao Tang
We demonstrate an approach to measure temporal correlations of photons in the near infrared range using frequency up-conversion. In this approach, the near infrared signal photons are converted into the visible range, in which highly efficient silicon

Multi-wavelength Pumping Technique for Up-conversion Single-photon Detectors

May 1, 2011
Author(s)
Lijun Ma, Joshua Bienfang, Oliver T. Slattery, Xiao Tang
We propose a multi-wavelength pumping technique to improve temporal resolution of up-conversion single-photon detectors. By using two-wavelength pumping we doubled the date rate of a quantum system beyond its original limitation.

Frequency Up-conversion Single Photon Detectors for Quantum Communication Systems

April 27, 2011
Author(s)
Lijun Ma, Oliver T. Slattery, Xiao Tang, Joshua Bienfang
Frequency up-conversion technology can be used to increase detection efficiency for near infrared photons, as has been demonstrated in fiber-based quantum communication systems. In a continuous wave pumped up-conversion detector, the temporal resolution is

Up-conversion Single-photon Detector Using Multi-wavelength Sampling Techniques

March 8, 2011
Author(s)
Lijun Ma, Joshua Bienfang, Oliver T. Slattery, Xiao Tang
The maximum achievable data-rate of a quantum communication system can be critically limited by the efficiency and temporal resolution of the system s single-photon detectors. Frequency up-conversion technology can be used to increase detection efficiency

An Application of Quantum Networks for Secure Video Surveillance

February 1, 2011
Author(s)
Alan Mink, Lijun Ma, Xiao Tang, Barry J. Hershman
In this chapter we have discussed the QKD protocol and its potential to secure video surveillance applications. We have shown examples of a QKD implementation along with reference to other implementations. We have also shown some innovations that can

Ultra Low Dark-count-rate Up-conversion Single Photon Detector

November 7, 2010
Author(s)
Xiao Tang, Lijun Ma, Oliver T. Slattery
We have demonstrated an ultra low noise up-conversion single photon detector using a periodically poled lithium niobate waveguide. The dark count rate of this detector is lower than 100 counts/second with 10% detection efficiency.
