B. Huttner et al., LOCAL BIREFRINGENCE MEASUREMENTS IN SINGLE-MODE FIBERS WITH COHERENT OPTICAL FREQUENCY-DOMAIN REFLECTOMETRY, IEEE photonics technology letters, 10(10), 1998, pp. 1458-1460
Measurements of intrinsic and induced birefringence of optical fibers
are performed at 1550 nm using the optical frequency-domain reflectome
try technique. The experiment confirms the theoretical analysis, which
predicts the appearance of oscillations on the detected Rayleigh back
scattering intensity, with periods equal to the polarization beat leng
th L-b and to L-b/2, Polarization mode-coupling length values are obta
ined from local birefringence and polarization mode dispersion measure
ments.
