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

Gordon W. Day, Douglas L. Franzen, Paul A. Williams
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 tenth Symposium on Optical Fiber Measurements, held

Rotating-polarizer polarimeter for accurate retardance measurement

September 1, 1997

Paul A. Williams, Allen Rose, Chih-Ming Wang
We demonstrate an automated polarimeter based on a rotating polarizer for the measurement oflinear retardance independent oflaser power and detector gain. The retardance is found when a curve is fitted to a unique normalization of the intensity response of
