Abstract

A technique for writing chirped-period gratings by UV exposure in photosensitive optical fibres is reported. Results are presented for gratings produced in boron-germania codoped fibres, hydrogen-loaded high-germania fibres, and hydrogen-loaded standard telecommunications fibres, with performance parameters ranging from 99% reflectivity with 7.5 nm bandwidth, to approximately 5% reflectivity over >17 nm bandwidth.
