Effects of temperature on the birefringence properties of polarisation maintaining fibres
Effects of temperature on the birefringence properties of polarisation maintaining fibres
Many optical fibre sensors such as interferometers and gyros require the transmission of stable colinear polarised light. External perturbations such as bends and twists, however, lead to variations in the output polarisation state of light guided by ordinary single-mode optical fibres (Payne et al (1)). Highly birefringent fibres attempt to overcome this difficulty by deliberately introducing levels of intrinsic birefringence Δβ in excess of that produced by external factors, thereby rendering the polarisation state immune to all but the most major perturbations. Such fibres are characterised by their modal birefringence B, defined as nx - ny = λ/2π ΔB, where nx and ny refer to the refractive indices x and y respectively. A commonly quoted figure of merit however, is the so-called beat length Lp = λ/B at a given wavelength.

Abstract
Many optical fibre sensors such as interferometers and gyros require the transmission of stable colinear polarised light. External perturbations such as bends and twists, however, lead to variations in the output polarisation state of light guided by ordinary single-mode optical fibres (Payne et al (1)). Highly birefringent fibres attempt to overcome this difficulty by deliberately introducing levels of intrinsic birefringence Δβ in excess of that produced by external factors, thereby rendering the polarisation state immune to all but the most major perturbations. Such fibres are characterised by their modal birefringence B, defined as nx - ny = λ/2π ΔB, where nx and ny refer to the refractive indices x and y respectively. A commonly quoted figure of merit however, is the so-called beat length Lp = λ/B at a given wavelength.
