A phase mask fiber grating and sensing applications

Abstract

This paper presents an investigation of a fabricated fiber grating device characteristics and its applications, using a phase mask writing technique. The use of a most common UV phase laser (KrF eximer laser), with high intensity light source was focussed to the phase mask for writing on a fiber optic sample. The device (i.e. grating) characteristic especially, in sensing application, was investigated. The possibility of using such device for temperature and strain sensors is discussed.
