Fabrication of integrated Ti:LiNbO3 waveguide polarizer
Author(s): Vadim Dobrusin; Shlomo Ruschin

Paper Abstract

The design and fabrication of an integrated waveguide polarizer in z-cut LiNbO3 crystals are reported. Single-polarization guiding is achieved by careful selection of Ti diffusion parameters exploiting the transverse electric/transverse magnetic (TE/TM) refractive index anisotropy. Fabricated Ti:LiNbO3 waveguide polarizers of 1.5 cm length exhibit less than 0.2-dB/cm propagation loss at TM and 33-dB extinction ratio as measured at 1.55-μm wavelength.
