Abstract

The temperature dependence of the spectral response of Bragg grating filters at 1550 nm, written in single-mode planar waveguides of As2S3 chalcogenide glasses, is presented. It was found that Bragg reflectance increases with temperature (corresponding to an increase as high as 4 dB of the transmission depth, from 20 °C to 50 °C), whereas the resonant wavelength shifts by ∼1 nm. The difference between temperature dependence of the structural properties for exposed and unexposed areas is thought to be responsible for the increase of refractive-index modulation depth. Two experimental techniques are used to further study the observed phenomena.
