Paper Abstract

We present a broadband DBR recorded with violet light (441.6 nm) by use of a holographic technique into Tiindiffused channel LiNbO3 waveguides, which were doped by proton-assisted copper exchange, giving unique possibility to reach an extremely high modulation of refractive index (≥5x10-4) within photorefractive grating. In a first approach we obtain a reflectivity of 17 % and bandwidth (FWHM) of 1.2 nm for IR light with center wavelength 1534.3 nm. Finally, we present the experimental data on specific spectral response of an asymmetric Fabry-Perot interferometer formed by broadband DBR and air-waveguide interface.
