TL;DR: The role of the mode field diameter in the characterization of single-mode fibers is examined in this article, where the most relevant definitions of this parameter are reviewed, and a comparative analysis of methods for its measurement is performed.

TL;DR: A finite difference method based on a Crank-Nicolson discretisation procedure has been implemented and applied to the analysis of propagation of optical beams in dielectric waveguides as mentioned in this paper.

TL;DR: In this paper, the authors compared various modeling techniques for the eigenmode analysis of integrated optical waveguides, and applied twelve different methods to the analysis of two typical III-V rib waveguide.

TL;DR: In this article, the refractive index distribution of singlemode optical fibres can be obtained from transmitted near-field intensity measurements, and the generalisation of the method from conventional fibres to noncircularly symmetric guides (e.g. polarisation-maintaining fibres) is discussed.

TL;DR: In this article, a new discretisation procedure based on a finite difference approach is presented for the analysis of arbitrary two-dimensional optical dielectric waveguides, which allows an accurate treatment of waveguide changes of geometry to be obtained.
