摘要: Isolation properties at different propagation directions have been studied for an optical barrier between two superposed planar waveguides produced by MeV He+ implantation in LiNbO3. The exists while the modes of double structure propagate along optic axis. spacing measured with a prism coupler features efficiently isolated waveguides. ‘‘vanishes’’ when directional angle extraordinary wave and axis exceeds 50°. In this case mode shows strong coupling that makes similar to single waveguide thickness.
