Rib wave-guides were fabricated with the use of selective, wet chemical etching of two-component wave-guide films SiO2:TiO2 which were obtained using sol-gel method. Photoresist was applied as a mask in the process. The etching of the films SiO2:TiO2 was carried out in water solution of ammonia fluoride. The paper presents the results of theoretical analysis as well as the power distributions in the fabricated strip wave-guides.
