A novel high-efficiency crystal/polymer composite material for nonlinear optics

Abstract

FOR practical applications in optoelectronic devices, nonlinear optical materials should ideally combine appropriate optical properties (that is, a nonlinear response to an electric field, characterized by second-harmonic generation) with the mechanical properties, such as strength and rigidity, required for ease of processibility. As reported here, we have developed a new class of material that combines these attributes, by growing aligned crystals of an optically nonlinear organic compound in a transparent polymer matrix. The host conveys desirable mechanical characteristics to the otherwise fragile organic crystals. The composites are transparent and non-scattering, with a refractive index that can be varied by modification of the polymer host. Given, in addition, the high chemical stability of these materials, we believe that they will have an important part to play in the development of optoelectronic devices.
