The differences of temperature characteristics of sol-gel waveguides for TE and TM modes are found and explained. Features of temperature dependence of effective refractive index at high temperatures are revealed and interpreted.integrated opticsoptical waveguideeffective refractive indexsol-gel methodoptical temperature coefficientинтегральная оптикаоптический волноводэффективный показатель преломлениязоль-гель технологиятермооптический коэффициент
