Abstract

Spectra evolutions of Bragg gratings written in the step-index multimode optical fibre are analyzed and investigated experimentally, which show that different kind gratings can be achieved with different irradiation pulses. Applications of multimode fibre Bragg gratings to optical sensing and optical communications are discussed. A chemical sensor based on an etched multimode fibre Bragg grating is demonstrated experimentally..
