This paper presents a theoretical investigation on the dispersion in graded-index silica glass
fibers under overfilled launching with equal excitation of modes. This theory incorporates …

We calculate the modal power distribution of a randomly and linearly polarized (LP)
multimode beam inside a cylindrical fiber core from knowledge of spatial-intensity profiles of …

This thesis describes an investigation into methods for controlling the mode distribution in
multimode optical fibres. The major contributions presented in this thesis are summarised …

The problem of signal degradation due to spatial filtration in graded-index fibers excited by
single-mode lasers is considered. In particular, a computer simulation of the interfering …

The frequency response and bandwidth of multimode silica glass fibers are investigated in
this paper. The theoretical model incorporates both wavelength and modal effects including …

A new fiber-optic method for quasi-distributed remote chemical sensing is described. The
technique is based on using a wavelength selective Bragg-grating radiation coupler for …

Backscattering measurements performed on test fibers perturbed by several serially placed
microbending sensors reveal the surprising result that the loss induced in a given sensor is …

In this paper, we report the modal dispersion of silica graded-index optical fibers as a
function of the input mode parameters and lunching conditions in local area network (LAN) …

Under certain assumptions the modal power distribution in optical multimode fibers can be
derived from either the near-or the far-field. We measured both intensities and compared the …

A theory with which one can calculate modal distributions within a multimode fiber excited by
a source of arbitrary spatial coherence, but within the mode-continuum limit, is presented …
