When subjected to bending they were found to be spectrally sensitive to bend orientation and displayed a strong polarisation dependence.

Review of long period fiber gratings written by CO 2 laser
This paper presents a systematic review of long period fiber gratings (LPFGs) written by the CO2 laser irradiation technique. Firstly, various fabrication techniques based on CO2 laser irradiations are demonstrated to write LPFGs in different types of optical fibers such as conventional glass fibers, solidcore photonic crystal fibers, and air-core photonic bandgap fibers. Secondly, possible mec...
متن کامل<Edited by Milan Brandt and Erol Harvey> POINT BY POINT FEMTOSECOND LASER INSCRIPTION OF FIBRE AND WAVEGUIDE BRAGG GRATINGS FOR PHOTONIC DEVICE FABRICATION
We present a flexible and rapid method for the production of Bragg gratings in a range of optical waveguides such as optical fibres and direct laser-written waveguides in bulk media. Using a low repetition rate (1 kHz) femtosecond laser, Bragg grating structures can be written in a point-by-point fashion (where each laser pulse inscribes one period of the Bragg structure) in both passive and ac...
متن کاملSingle-mode grating reflection in all-solid photonic bandgap fibers inscribed by use of femtosecond laser pulse irradiation through a phase mask.
Single-mode Bragg grating reflection has been achieved in all-solid photonic bandgap fibers by use of femtosecond laser pulse irradiation through a phase mask. The grating created is confined to the all-silica fiber core region and exhibits higher thermal stability than other type I femtosecond-pulse-induced gratings.
متن کاملImplementation of vectorial bend sensors using long-period gratings UV-inscribed in special shape fibres
We report the implementation of vector bending sensors using long-period gratings (LPGs) UV-inscribed in flat-clad, four-core and D-shaped fibres. Our experiments reveal a strong fibre-orientation dependence of the spectral response when such LPGs are subjected to dynamic bending, which provided an opportunity to realize curvature measurement with direction recognition.
متن کاملTemperature insensitive long period grating sensors in photonic crystal fibre
A Long Period Grating was fabricated in endlessly single mode photonic crystal fibre using a spatially-periodic electric arc discharge. The sensing characteristics of the grating were studied and it was found to possess an insensitivity to temperature, a bend sensitivity of 3.7 nm.m and a strain sensitivity of -2.0 pm/με. Introduction: Long period gratings (LPGs) consist of a large scale (hundr...
