In this chapter, after presenting a brief review of the various types of optical waveguides, we outline the key principles and parameters which describe and define the operation of optical waveguides and fibres The ways in which propagation through optical fibres affects the properties of the guided waves are discussed, including dispersion and non linear effects Power transfer between propagating waves is essential to the operation of a number of components and the fundamentals of coupling theory are reviewed In summary, the theory given provides the foundation for understanding the detailed operation of a wide variety of optical components and systems based on optical fibre technologyread more

Modes of optical waveguides
Allan W. Snyder,William R. Young +1 more
TL;DR: In this article, a simple method is presented for finding the modes on those optical waveguides with a cladding refractive index that differs only slightly from the core, and the resulting modal fields and their progagation constants display the polarization properties of the waveguide contained within the ∇ ∊ term of the vector wave equation.

Single-mode optical waveguides.
TL;DR: An efficient and powerful technique has been developed to treat the problem of wave propagation along arbitrarily shaped single-mode dielectric waveguides with inhomogeneous index variations in the cross-sectional plane based on a modified finite-element method.

Preservation of polarisation in optical-fibre waveguides with elliptical cores
TL;DR: In this paper, an analysis of the propagation characteristics shows that there is a point below the higher-mode cutoff where the difference in group velocities between the two fundamental modes is zero but where there is large enough difference in the phase velocity to preserve polarisation.

Fabrication of single-mode fibres exhibiting extremely low polarisation birefringence
TL;DR: In this paper, the relative effects of core ellipticity and stress-induced birefringence on fiber polarisation properties were investigated and it was found that a reduction in core stress levels is necessary to obtain low-birefurringence fibres.
