## Abstract The synthesis of an oriented liquidโcrystalline photoresponsive polymer, prepared by polymerization of monoโ and diโacrylates, both of which contain azobenzene chromophores, is reported. The prepared freeโstanding polymer film shows strong reversible photoinduced deformation upon exposu
## Abstract Liquid crystalline (LC) networks with macroscopically uniaxial molecular orientation were prepared by photopolymerization of mixtures of LC monoโ and diacrylates and a donorโacceptor azobenzene compound in a homogeneous glass cell at the nematic phase, and their photoresponsive properti
## Abstract Grating waveguide couplers with a flat surface were fabricated in an azobenzene liquidโcrystalline 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
