Precision measurement of modal birefringence of highly birefringent fibers by periodic lateral force

Abstract

Modal birefringence of highly birefringent fibers can be measured nondestructively by the elastooptic modulation method. Based on this modulation method, a new method for precisely measuring the wavelength dependence of modal birefringence in highly birefringent fibers is presented using an incoherent light source such as a fiber Raman laser.

Distributed group birefringence measurement in a polarization-maintaining fiber using optical frequency-domain reflectometry

“…Many of them rely on measuring the transmission signals by manipulating the test fibers [1][2][3], modulating the optical phase or wavelength of the optical source, and using low coherence interferometric techniques [4][5][6][7]. The methods mentioned above can only give effective values contributed by the entire fiber under test owing to the transmission based measurement nature.…”

Spectral-domain measurement of phase modal birefringence in polarization-maintaining fiber

“…A standard technique of time-domain tandem interferometry [3] uses processing of either a single interferogram [4,5] or a series of interferograms at different wavelengths [6,7,8] recorded in a tandem interferometer. The latter technique is a modification of a lateral force method proposed and demonstrated for precisely measuring the phase modal birefringence in PMFs [9]. Recently, a new measurement technique employing a low-resolution spectrometer at the output of a tandem configuration of a Michelson interferometer and an elliptical-core PMF [10,11] has been used to measure the dispersion of group modal birefringence over a wide spectral range [11].…”
