摘要
A method of manufacturing a polymer film having second order non-linear optical properties which has excellent stability of orientated molecules and does not become disorientated, and a polymer film and a non-linear optical element are provided. A polymer solution is placed between two substrates, which are disposed substantially perpendicular with respect to a rotating stand and substantially symmetrical with respect to a rotation axis of the rotating stand, and the rotating stand is rotated. A polymer film having second order non-linear optical properties is formed by the centrifugal force generated at the polymer solution. The polymer solution is a solution formed by dissolving, in an organic solvent, at least one of (1) a host-guest polymer in which low molecular weight compounds are dispersed in polymers, (2) a modified polymer in which regions which exhibit a function of second order non-linear optical properties are chemically modified in polymer side chains and/or a polymer main chain, and (3) a crosslinked polymer. Among these, modified polymers are particularly preferable.
