Yupapin %J Songklanakarin Journal of Science and Technology %D 2003 %I Songkla University %X 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. %K fiber bragg grating %K optical sensor %K optical signal processing %U http://www.sjst.psu.ac.th/journal/25-5-pdf/07fiber.pdf
