Optical pulse compression using similariton propagation in an optical fibre with decreasing dispersion has been demonstrated for the first time. This scheme is a practical application of sech-similariton solution to generalized nonlinear schrodinger equation(NLSE) distributed coefficients recently found self similarity technique. The profile constructed comb-profile approximation technique and ...

-Radio-over-Fibre (RoF) is an optical communication technique based on the transmission of standard wireless radio signals though optical Fibre in their native format. The optical Fibre provides a huge bandwidth that can support a variety of wireless systems, regardless of their frequency bands, being protocol-transparent which is reflected in great network flexibility. Radio-overFibre techniqu...

A distributed optical fibre dynamic strain sensor with high spatial and frequency resolution is demonstrated. The sensor which uses φ-OTDR interrogation technique exhibited a higher sensitivity thanks to an improved optical arrangement and a new signal processing procedure. The proposed sensing system is capable of fully quantifying multiple dynamic perturbations along a 5km long sensing fibre ...

We present a powerful approach towards full understanding of laser light propagation through multimode optical fibres and control of the light at the fibre output. Transmission of light within a multimode fibre introduces randomization of laser beam amplitude, phase and polarization. We discuss the importance of each of these factors and introduce an experimental geometry allowing full analysis...

A regenerated optical fibre Bragg grating that survives temperature cycling up to 1,295°C is demonstrated. A model based on seeded crystallisation or amorphisation is proposed.

POF offers many benefits to the user. It is lightweight, robust, cheap and easy to install. A simple sharp blade can be used to cut POF, without the need for polishing afterwards. The use of 650nm red light (LED) makes it completely safe. This safety feature brings additional benefits to the installer, as red light can be easily seen by the human eye to diagnose if the link is good. Perhaps tho...

In recent times a remarkable breakthrough has occurred in the field of optical frequency measurement and synthesis. For the first time it is now possible to generate arbitrary waveform light pulses, perform accurate optical frequency synthesis and accurately measure the frequency of optical frequency signals. These long dreamed of possibilities have been delivered because of the existence of tw...

We report experimental measurements of the strain and temperature sensitivity of the optical phase in a singlemode polymer optical fibre. These values were obtained by measuring optical path length change using a Mach-Zender interferometer.

The use of an optical-fibre polarimeter as a chemical sensor is demonstrated. The compound to be detected is allowed to adsorb onto a decladded 5 cm length of the fibre. The fibre is polarization maintaining with an elliptical fibre core and a D-shaped geometry. The overall retardation stability of this fibre polarimeter is x0.5 x 2x rad m-’ K-‘. With this sensor adsorption processes of protein...
