This paper deals with communication using optical fibres. The transmission using high bandwidth can handle vast amounts of information, which can be further improved by reduction in fibre losses, increase in data rates and distances, development of optical sources and detectors compatible with fibres. The recent development in the area of fibre optic communication as well as the advances in dif...

In this intelligent fault detecting system in an optical fibre used to find the fault in optic fibre line. To design a fault monitoring module and find the fault in the line says across the customer sides. The idea behind this module is to monitor the received power supply in optical fibre using a Microcontroller. Laser output power monitoring circuit is designed using ISIS simulator to monitor...

Control of dispersion in fibre optical waveguides is of critical importance to optical fibre communications systems and more recently for continuum generation from the ultraviolet to the mid-infrared. The wavelength at which the group velocity dispersion crosses zero can be set by varying fibre core diameter or index step. Moreover, sophisticated methods to manipulate higher-order dispersion so...

Current research efforts are focussed on overcoming the apparent limits of communication in single mode optical fibre resulting from distortion due to fibre nonlinearity. It has been experimentally demonstrated that this Kerr nonlinearity limit is not a fundamental limit; thus it is pertinent to review where the fundamental limits of optical communications lie, and direct future research on thi...

C. Michel, S. Tascu, V. Doya, O. Legrand, F. Mortessagne In this paper, we present a non-standard fibre amplifier specially designed to amplify scar modes of a multimode chaotic optical fibre. More precisely, we introduce Ytterbium in the optical fibre as a gain medium localised on the maximum of intensity of the scar modes. After briefly recalling the relevance of a chaotic optical fibre as a ...

In many photonics applications, especially in optical fibre based systems, the state of polarization of light remains so far an elusive uncontrolled variable, which can dramatically affect the performances of that systems and which one would like to control as finely as possible. Here, we experimentally demonstrate light-by-light polarization control via a nonlinear effect occurring in single m...
