Abstract: A possibility of designing optical waveguide devices based on sol – gel SiO₂ – TiO₂ films using the temperature dependence of the effective refractive index is shown. The dependences of the device characteristics on the parameters of the film and opticalsystem elements are analysed. The operation of a temperature recorder and a temperature limiter with a resolution of 0.6 K mm^-1 is demonstrated. The film and output-prism parameters are optimised.

Keywords: sol – gel film waveguides, effective refractive index, temperature recorder, temperature limiter.
