Calibration of free-space and fiber-coupled single-photon detectors

Author(s)
Thomas Gerrits, Alan L. Migdall, Joshua C. Bienfang, John H. Lehman, Sae Woo Nam, Oliver T. Slattery, Jolene D. Splett, Igor Vayshenker, Chih-Ming Wang
We present our measurements of the detection efficiency of free-space and fiber-coupled single- photon detectors at wavelengths near 851 nm and 1533.6 nm. We

Digital Radiometer for Traceable Spectrum Sensing

Author(s)
Xifeng Lu, Dazhen Gu, Daniel G. Kuester
This paper describes a metrology instrument designed for detecting noise and interference in digital communications. A quadrature detector downconverts in-phase

Radiation Pressure Laser Power Meter for Industrial Laser Machining

Author(s)
Aly Artusio-Glimpse, Ivan Ryger, Natalia A. Azarova, Paul A. Williams, John H. Lehman
Demonstration and validation of a linear radiation pressure-based high-power laser power meter is presented. To date, this device is the most promising real

A Cryogenic Quantum-Based RF Source

Justus A. Brevik, Alirio De Jesus Soares Boaventura, Manuel C. Castellanos Beltran, Christine A. Donnelly, Nathan E. Flowers-Jacobs, Anna E. Fox, Peter F. Hopkins, Paul D. Dresselhaus, Dylan Williams, Samuel P. Benz
We performed a preliminary calibrated measurement of the output power of a Josephson arbitrary waveform synthesizer up to 1 GHz. We present the results and

Evaluating Unicast and MBSFN in Public Safety Networks

Author(s)
Chunmei Liu, Chen Shen, Jack Chuang, Richard A. Rouil, Hyeong-Ah Choi
Public safety incidents typically involve a significant amount of group traffic and have a stringent requirement of connection reliability. Hence multicast

Synchronizing Stock Market Clocks to UTC(NIST)

Author(s)
Michael A. Lombardi
To reduce the possibility of fraudulent activity and market manipulation, the world's major stock exchanges require every clock involved in a stock market

Graphene quantum Hall effect devices for AC and DC resistance metrology

Author(s)
Mattias Kruskopf, Dinesh K. Patel, Chieh-I Liu, Albert Rigosi, Randolph Elmquist, Yicheng Wang, Stefan Bauer, Yefei Yin, Klaus Pierz, Eckard Pesel, Martin Goetz, Jurgen Schurr
The frequency dependence of the quantized Hall resistance at alternating current results from capacitive losses inside the sample as well as between the sample

AC and DC Quantized Hall Array Resistance Standards

Author(s)
Randolph E. Elmquist, Mattias Kruskopf, Dinesh K. Patel, I Fan Hu, Chieh-I Liu, Albert F. Rigosi, Alireza R. Panna, Shamith U. Payagala, Dean G. Jarrett
Quantized Hall array resistance standards (QHARS) span values from 100 (ohm) to 1 M(ohm) and demonstrate precision approaching that of single devices. This

Ultrafast waveform metrology: A first international comparison

Author(s)
Mark Bieler, Paul Struszewski, Ari Feldman, Jeffrey Jargon, Paul D. Hale, Pengwei Gong, Wen Xie, Chuntao Yang, Zhigang Feng, Kejia Zhao, Zhijun Yang
We report on the first international comparison in ultrafast waveform metrology. To this end, the frequency and time responses of a photodiode with a nominal
