High-power nonlinearity of optical fiber power meters at 1474 nm

May 11, 2005
Author(s)
Igor Vayshenker, Ralph Swafford, Shao Yang
We have developed a system to measure the nonlinearity of optical fiber power meters (OFPMs) at a maximum power of 0.6 W at 1474 nm. The system is based on the triplet superposition method. This system measures nonlinearity of OFPMs using correction

Igor Vayshenker, Ralph Swafford, Shao Yang
We have developed a system for measuring the nonlinearity of optical fiber power meters at maximum power of 2 W. This system is based on the triplet superposition method. This system provides an accurate determination of optical power meter nonlinearity by

Intramural comparison of NIST laser and optical fiber power calibrations

Author(s)
John H. Lehman, Igor Vayshenker, David J. Livigni, Joshua A. Hadler
The responsivity of two optical detectors was determined by the method of direct substitution in four different NIST measurement facilities. The measurements were intended to demonstrate the determination of absolute responsivity as provided by NIST

Optical-Fiber Power Meter Comparison between NIST and PTB

October 1, 2003
Author(s)
Igor Vayshenker, Holger Haars, Xiaoyu X. Li, John H. Lehman, David J. Livigni
We describe the results of a comparison of reference standards between the National Institute of Standards and Technology (NIST-USA) and Physikalisch-Technische Bundesanstalt (PTB-Germany) at nominal wavelengths of 1300 and 1550 nm using an optical-fiber

Comparison of Optical-Power Meters Between the NIST and the PTB

Author(s)
Igor Vayshenker, Holger Haars, John H. Lehman, David J. Livigni
We describe the results of a comparison of optical-power meters undertaken by the National Institute of Standards and Technology (NIST, USA) and the Physikalisch-Technische Bundesanstalt (PTB, Germany) at nominal wavelengths of 1300 nm and 1550 nm. Both

Comparison of Reference Standards for Measurements of Optical-Fibre Power

S. V. Tikhomirov, A. I. Glazov, M. L. Kozatchenco, V. E. Kravtsov, A. B. Svetlichny, Igor Vayshenker, Thomas Scott, Douglas L. Franzen
National reference standards for determining optical-fibre power maintained by the National Institute of Standards and Technology (NIST, USA) and the All-Russian Research Institute for Optophysical Measurements (VNIIOFI, Russian Federation) were compared

Optical Fiber Power Meter Nonlinearity Calibrations at NIST

August 1, 2000
Author(s)
Igor Vayshenker, Shao Yang, Xiaoyu X. Li, Thomas Scott, Christopher L. Cromer
We describe a system for measuring the response nonlinearity of optical fiber power meters and detectors over a wide power dynamic range at telecommunication wavelengths. The system uses optical fiber components and is designed to accommodate commonly used

Optical Fiber Power Meter Calibrations at NIST

Igor Vayshenker, Xiaoyu X. Li, David J. Livigni, Thomas Scott, Christopher L. Cromer
NIST has established measurement services for the calibration of optical fiber power meters at the three nominal wavelengths of 850, 1300, and 1550 nm using either collimated beam or optical fiber/connector configurations. This paper describes the

Author(s)
Igor Vayshenker, Xiaoyu X. Li, David J. Livigni, Thomas Scott
We describe NIST measurement services for the calibration of optical fiber power meters. To augment the absolute power measurements NIST provides nonlinearity, spectral responsivity, and uniformity measurements. We explain the measurement standards

Transfer function approach to the experimental determination of mode transfer matrices

July 20, 1990
Author(s)
Shao Yang, Igor Vayshenker, D. R. Hjelme, I. P. Januar, A. R. Mickelson
An improved scheme for characterization of multimode fiber systems is investigated. Characterization with transfer matrices requires multiple measurements for each component. The transfer function approach herein investigated requires only a single launch

Transfer function analysis of measured transfer matrices

August 1, 1989
Author(s)
Shao Yang, Igor Vayshenker, A. R. Mickelson
Measurements of mode transfer matrices of various multimode fiber optic connectors are presented. To analyze the accuracy and repeatability of such measurements, a theoretical framework which employs mode transmission functions is derived. It is shown that
