Abstract
The research results involving two-component waveguide films SiO2:TiO2 produced in sol–gel technology are presented. The waveguide films were deposited on soda-lime glass substrates using dip-coating method. The titled layers were fabricated as waveguide layers for application in planar evanescent wave sensors. The such prepared slab waveguides possess low optical losses and they demonstrate a possibility of formation of the photo induced optical second harmonic generation (SHG) which is observed due to photoinduced charge density non-centrosymmetry. In the present work we explore additionally the dependences of the photoinduced SHG versus the power density and the time of treatment.
