In the paper the hybrid optical fibre pH sensor based on absorption and refraction is presented. As an optical transducer pH-sensitive metyl orange dye was exploited. Additionally, variations of the refractive index of the porous silica film with the pH of solution were also utilized. The film, in which the dye was encapsulated, was prepared by means of the sol-gel method and deposited onto the fibre core. It was found that the sensitivity for acidic (2÷6) and basic (7÷10) ranges were 1,0 dB/pH and 3,5 dB/pH, respectively.
