TLDR
A method that combines an interferometric technique with wavelength scanning and permits a precise nondestructive measurement of the birefringence along different sections of a long optical fiber is described.Abstract:
We describe a method for measuring modal birefringence in optical fibers. It combines an interferometric technique with wavelength scanning and permits a precise nondestructive measurement of the birefringence along different sections of a long optical fiber. The experimental results for high-birefringence fibers, 10 and 100 m long, are presented. An accuracy of approximately 0.1% is achieved in the spectral range of 600–850 nm.read more

Polarization-Mode Dispersion
TL;DR: In this article, it is shown that fluctuations in the polarization mode and fiber birefringence produced by the environment lead to dispersion that varies statistically with time and frequency.

White-light spectral interferometry with the uncompensated Michelson interferometer and the group refractive index dispersion in fused silica
TL;DR: In this paper, the authors measured the equalization wavelength as a function of the displacement in the Michelson interferometer by a low-resolution miniature fiber-optic spectrometer and confirmed that the group refractive index dispersion in the beam splitter made of fused silica agrees well with that resulting from the Sellmeier dispersion equation.

TL;DR: In this paper, the use of optical reflectometry as a tool to characterize fiber birefringence is discussed, and the application of polarization-OTDR to polarization mode dispersion and polarization dependent loss measurements is also discussed.

TL;DR: A new and simple method for measuring the wavelength dependence of phase modal birefringence in a polarizationmaintaining fiber based on application of a lateral pointlike force on the fiber that causes strong coupling between polarization modes and utilizes their interference resolved as the channeled spectrum.

Complete Characterization of Polarization-Maintaining Fibers Using Distributed Polarization Analysis
TL;DR: In this article, a ghost-peak-free distributed polarization crosstalk analyzer (DPXA) was used to obtain all polarization related parameters of polarization-maintaining (PM) fibers.

Evolution of polarization along a single‐mode fiber
TL;DR: In this paper, the local parameters of linear and circular birefringence are measured along a singlemode optical fiber by electrooptic and magneto-optic modulation of the polarization in the fiber.

Wavelength dependence of birefringence in highly birefringent fibers.
TL;DR: A simple technique is used to measure the wavelength dependence of the bireFringence in highly birefringent fibers, which shows that in stress-induced fibers the stress and shape bires reinforce each other or partially cancel, depending on the wavelength.

Measurement of fiber birefringence by wavelength scanning: effect of dispersion
TL;DR: Scanning the wavelength in high-birefringence fibers inherently measures the groupdelay difference, and not the phase delay difference, between the two polarization modes.

TL;DR: A white-light interference phenomenon arising between polarization modes as a result of mode coupling induced by a pointlike lateral force applied in approximately one half the length of the tested fiber permits the use of a Wollaston prism without a delay line as an analyzing interferometer.
