Improved materials are required for active optical devices, including electro-optic and acousto-optic modulators, switches and tunable filters, as well as for new devices based on degenerate four-wave mixing. New materials are also needed for surface acoustic wave SAW applications where the lack of materials with large coupling coefficients and inherent temperature stability has limited the bandwidth of SAW devices and made them unsuitable for many microwave applications. In addition, electro-optic and acousto-optic devices are materials limited because the materials currently available are inefficient in terms of power required and often absorb light in the regions in which operation is desired. The primary objectives of this program include the synthesis and evaluation of new ternary chalcogenides for nonlinear and acoustical applications, and subsequently, the investigation of these materials for applications involving the electro-optic effect, degenerate four-wave mixing and surface acoustic wave technology.
