Abstract
Abstract A process for preparing an organic compound thin film for use in an optical device including steps of forming a multiplicity of geometric linear streaks with microscopic unevenness in section on a substrate at least whose surface is made up of an amorphous organic polymer layer; thereafter vapor-depositing on the surface an organic compound capable of exhibiting non-linear optical characteristics to form a non-linear optical material film.
