Paper Abstract

In this paper the behaviour of fiber Bragg gratings as temperature and strain sensors is presented. The formation, using a photolitographic method, and characterization of those narrow-band filter are also described. The filter response, tunable in frequency due to mechanical strain and temperature change, has shown good linearity over a wide range of both strain and temperature variations. Arrays of up to five gratings, with a peak separation of about 1 nm, have been written using the same phase mask.
