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

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

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.

Study on Noise Reduction in Up-conversion Single Photon Detectors

September 9, 2010
Author(s)
Lijun Ma, Oliver T. Slattery, Xiao Tang
Up-conversion single photon detector technology has been established as efficient for photons in near infrared range. However, its dark count rate is a major concern for some applications in quantum optics. We have theoretically and experimentally studied

Ultra Sensitive NIR Spectrometer Based on Frequency Up-conversion Detector

April 7, 2010
Author(s)
Lijun Ma, Oliver T. Slattery, Xiao Tang
We developed a spectrometer for signals at single photon levels in the near infrared (NIR) region based on a tunable up-conversion detector. This detector uses a 5-cm periodically poled lithium niobate (PPLN) waveguide to convert NIR photons to a shorter

1310 nm Differential Phase Shift QKD System Using Superconducting Single Photon Detectors

Xiao Tang, Lijun Ma, Sae Woo Nam, Burm Baek, Oliver T. Slattery, Alan Mink, Hai Xu, Tiejun Chang
We have implemented a differential-phase-shift (DPS) quantum key distribution (QKD) system at 1310 nm with superconducting single photon detectors (SSPD). The timing jitter of the SSPDs is small and its dark counts are very low. 1310 nm is an ideal quantum

Xiao Tang, Oliver T. Slattery, Lijun Ma
A compact scheme for high-speed frequency doubling and down-conversion on a single dual-element PPKTP waveguide is investigated. Optimal temperature is achieved and photon pair coincidence is observed at over GHz repetition rate with pulsed pump input

Alan Mink, Lijun Ma, Anastase Nakassis, Haolang Xu, Oliver T. Slattery, Barry J. Hershman, Xiao Tang
We have begun to expand the NIST quantum key distribution (QKD) system into a quantum network to support secure cryptography. We are starting with a simple three-node network, one Alice switched between Bob1 and Bob2. To support such a quantum network, we

Hai Xu, Lijun Ma, Oliver T. Slattery, Xiao Tang
This paper describes the detection of single photons, which have been transmitted through standard fiber at the telecom wavelength of 1310 nm. Following transmission, the 1310-nm photon is up-converted to 710 nm in a periodical-poled LiNbO3 (PPLN)
