## 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
