## Abstract Grating waveguide couplers with a flat surface were fabricated in an azobenzene liquid‐crystalline polymer film by holographic lithography using Ar^+^ laser beams at 488 nm. When a probe beam at 633 nm was incident to one grating of a grating waveguide coupler, the beam propagated in th

## Abstract The finite‐element analysis method based on the hybrid variational principle is proposed for analysis of the dispersion characteristic of periodic surface acoustic waveguides with a one‐wavelength period. A new formulation is used for finite element approximation applied to the periodic
