Abstract

In this work we present a specially designed high resolution electromechanical system to be used with a cw CO₂ Laser to fabricate high quality long period grating sensors (LPG). We also describe the experiments carried out to measure the resulting enhanced transmission spectra of the fabricated LPG and to measure their response as temperature sensors. Sharp and well pronounced spectral peaks were obtained reaching 30dB. Sensitivity values of 118 pm/°C were easily obtained without any fiber coating. Wide range temperature coverage (20 - 600 °C) was attained by making use of two distinctive peaks of the transmission spectrum.
