Backscattering Measurement of Bending - Induced Birefringence in Single Mode Fibres
core were investigated. It was shown from the measurement that the beat length was about L = 23 mm (birefringence B = 5 x 10") and the state of linear polarisation of the incident light beam was maintained up to 0-6 kg/cm of the concentrated force when the incident plane of polarisation was coincident with the major axis of the fibre. It was also shown that the degree and the plane of polarisat...
متن کاملNegligible birefringence in dual-mode ion-exchanged glass waveguide gratings.
Polarization dependence of UV-written Bragg gratings in buried ion-exchanged glass waveguides is investigated. A polarization-dependent shift in Bragg wavelength of less than 0.02 nm is measured, both for the even and the odd modes of a laterally dual-mode waveguide. The measured wavelength shift corresponds to a waveguide birefringence of the order of 10(-5), which is negligible for most appli...
متن کاملPolarization mode dispersion of spun fibers with randomly varying birefringence.
We show analytically how periodic spinning affects the polarization mode dispersion of a fiber in three different practical regimes that are determined by the values of three length scales: the beat length, the birefringence correlation length, and the spin period. We determine in which limits the spin is effective in reducing the mean differential group delay.
متن کاملPolarization mode coupling in long single-mode fibres
In this paper we look at the polarization state evolution of light propagating in long, birefringent, singlemode fibres in the presence of mode coupling. We show first that there always exist two orthogonal linear input polarizations which lead to linear output polarization for monochromatic light. The applicability of the coupled power equations is discussed and it is shown that they cannot be...
