PMD measurement techniques and how to avoid the pitfalls

November 1, 2004
Author(s)
Paul A. Williams
This chapter presents a practical guide to PMD measurements including descriptions of the various measurement techniques and discussion of their associated sources of measurement error. Methods for mitigating these error sources are also discussed.

Technical Digest, Symposium on Optical Fiber Measurements 2004

September 1, 2004
Author(s)
Paul A. Williams, Gordon W. Day
This digest is made up of technical papers presented at the 13th biennial Symposium on Optical Fiber Measurements (SOFM 2004)in Boulder, Colorado, September 28-30, 2004. Paper categories include wavelength metrology, nonlinear measurements, fiber

Key metrology considerations for fiber Bragg grating sensors

March 14, 2004
Author(s)
Shellee D. Dyer, Paul A. Williams, Robert J. Espejo, Jonathan D. Kofler, Shelley M. Etzel
We discuss the current status of fiber Bragg grating (FBG) sensor metrology. High-accuracy wavelength measurements are critical for FBG strain sensors, because wavelength measurement uncertainties even as small as 1 pm lead to an uncertainty of nearly 1

Recent Progress in Polarization Mode Dispersion Measurement

October 1, 2003
Author(s)
Kent B. Rochford, Paul Leo, D Peterson, Paul A. Williams
Measurement of polarization mode dispersion (PMD) spans from precise component characterization of differential group delay (DGD) to system characterization of mean DGD and dynamic PMD properties. We describe recent advances and issues in these varied

Technical Digest Symposium on Optical Fiber Measurements, 2002

September 1, 2002
Author(s)
Paul A. Williams, Gordon W. Day
This digest contains the papers presented at the 2002 Symposium on Optical Fiber Measurements, a 2-1/2 day forum devoted to measurements of fibers, integrated optics, components and systems. Topics covered include measurement of polarization-mode

PMD Measurement Techniques - Avoiding Measurement Pitfalls

June 1, 2002
Author(s)
Paul A. Williams
Polarization-mode dispersion (PMD) is an interesting phenomenon. Unfortunately, interesting usually means complicated, and that is definitely the case with PMD. These complications can be troublesome when attempting to measure PMD. This presentation has

Fiber and Component Metrology for High-Speed Communications

January 1, 2002
Author(s)
Tracy S. Clement, Paul D. Hale, Paul A. Williams
Increased data rates require improved measurements. We give specific guidance to avoid measurement pitfalls in two critical high data rate areas: Polarization-mode dispersion and transmitter/receiver frequency response. For audiences familiar (not expert)

Optical Metrology for Wavelength-Division-Multiplexed Fiber Communications

March 1, 2001
Author(s)
Sarah L. Gilbert, Shellee D. Dyer, Paul A. Williams, Allen Rose
In response to rapid changes in fiber-optic technology, the Optoelectronics Division of the National Institute of Standards and Technology has been developing techniques and standards to support the measurement of optical components and subsystems used in

Technical Digest, Symposium on Optical Fiber Measurements, 2000

September 1, 2000
Author(s)
Paul A. Williams, Gordon W. Day
Polarization mode dispersion (PMD), multimode fiber parameters, fiber geometry and chromatic dispersion mapping in fibers are some of the measurement issues in this digest of papers presented at the Symposium on Optical Fiber Measurements held September 26

NIST artifact standards for fiber optic metrology

January 1, 2000
Author(s)
Paul A. Williams
The primary means of transferring fiber optic calibration metrology at the National Institute of Standards and Technology is through artifact standards called Standard Reference Materials (SRM). NIST currently provides SRMs for fiber geometry (fiber

Technical Digest, Symposium on Optical Fiber Measurements, 1998

January 1, 1998
