Abstract

Ti:LiNbO3 waveguide polarizers were obtained by an epitaxial growth of a Zn-doped LiNbO3 layer on the Ti:LiNbO3 waveguide. The film growth was carried out by a liquid-phase-epitaxy technique using a Li2O-V2O5 flux. Such an X-cut waveguide polarizer achieved a TE-mode (extraordinary ray) propagation with an extinction ratio over 30 dB at a light wavelength of 1.55 μm. This technique can be easily applied to Z- and Y-cut waveguide polarizers with TM-aid TE-mode propagation, respectively.
