Abstract
We report the first fabrication and investigation of strongly coupling Bragg reflector gratings in proton exchanged LiNbO3 stripe waveguides. A filter bandwidth of 2.5 nm centered at 1.504 μm with a transmission drop of -28 dB was achieved for TM polarization in Z-cut material. These grating properties are compared with those of identically fabricated gratings in Ti:LiNbO3 stripe waveguides, where less localized field distributions result in a weaker coupling strength. The Bragg reflector gratings in Ti:LiNbO3 stripe waveguides were theoretically analyzed using coupled mode theory with numerically (finite element method) calculated field distributions.
