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

Thomas Gerrits, Alan L. Migdall, Joshua C. Bienfang, John H. Lehman, Sae Woo Nam, Jolene D. Splett, Igor Vayshenker, Chih-Ming Wang
We measure the detection efficiency of single-photon detectors at wavelengths near 851 nm and 1533.6 nm. We investigate the spatial uniformity of one free-space

Cryogenic Primary Standard for Optical Fibre Power Measurement

Author(s)
Malcolm G. White, Zeus Ruiz, Christopher S. Yung, Igor Vayshenker, Nathan A. Tomlin, Michelle S. Stephens, John H. Lehman
NIST has completed commissioning a new, state-of-the-art cryogenic primary standard for optical fibre power measurement and calibration. It establishes for the

Detecting Single Infrared Photons with 93 % System Efficiency

Author(s)
Francesco F. Marsili, Varun B. Verma, Jeffrey A. Stern, Sean D. Harrington, Adriana E. Lita, Thomas Gerrits, Igor Vayshenker, Burm Baek, Matthew D. Shaw, Richard P. Mirin, Sae Woo Nam
Single-photon detectors (SPDs) are nonlinear transducers that respond to the absorption of one or more photons with an electrical signal1. SPDs at near infrared

International comparisons of optical fiber power measurements

Author(s)
Igor Vayshenker, David J. Livigni, Xiaoyu X. Li, John H. Lehman
We discuss the results of optical fiber power meter (OFPM) measurements at 1310 and 1550 nm made by NIST and seven national measurement institutes (NMIs). We

Optical fiber power meter comparison between NIST and NIM

Connector-induced offsets in optical fiber power meters

Author(s)
Igor Vayshenker, Xiaoyu X. Li, Darryl A. Keenan
We discuss issues related to calibration of optical fiber power meters. The power readings may vary when using various types of fiber connectors, or even the
