Abstract
A nonlinear optical material is provided by mixing a polymer liquid crystal having a chiral center and a nonlinear optical compound. The polymer liquid crystal may be a ferroelectric polymer liquid crystal. The nonlinear optical material is preferably in the form of a solid solution. A nonlinear optical device is formed by orienting the nonlinear optical material to provide an optical member.
