Optical fibres: the southampton scene

Tailored optical fibres

The paper defines the field of special optical fibers. Classification of tailored optical fibers was introduced. The characteristics of main families of such fibers were presented. There were discussed the following fibers: isotropic made of soft glass, of complex refraction – including ring-index, polarization maintaining and polarizing, elliptical, holey with macro holes and porous, nonlinear...

On the soliton generation in optical fibres

This is a comment on a recent paper by Burzlaff. His paper is devoted to the investigation of optical soliton generation for special input pulses within the framework of the non-linear Schrodinger equation. This comment demonstrates that the main result by Burzlaff, namely the threshold condition for soliton generation, may be obtained in a general form for any initial pulse with a constant pha...

Composite Material and Optical Fibres

A bottleneck for optical fibres.

authors stimulated Cos cells with epidermal growth factor, they first detected activated Ras at the nearby plasma membrane. Active Ras then rapidly spread into the body of the cell, probably reflecting the internalization of a signalling complex composed of Ras, a guanine-nucleotide-exchange factor and perhaps the receptor. In PC12 cells that were induced to differentiate with nerve growth fact...

Supercontinuum Generation In Optical Fibres

In this work, a high power Ytterbium pump laser was used in a quasicontinuous wave (CW) pump scheme to generate supercontinua in two different optical fibres, a depressed cladding, graded index highly nonlinear fibre (HNLF), and a solid core photonic crystal fibre (PCF). Pumping a 300 m length of the HNLF with a peak pump power of 140 W, a continuum with a spectral flatness of 5 dB over 1000 nm...
