The influence of temperature on the reflectivity<br>of symmetrical metal-cladding optical waveguide (SMCOW) is<br>studied theoretically by means of single-factor investigation under<br>spectral and angular interrogation mode of operation. The theoretical<br>model for temperature dependence of reflectivity includes<br>the temperature dependence of refractive index and thickness<br>of guiding layer, the temperature dependence of the metal film<br>thickness and metal-dielectric functi
