New Materials for Infrared Transmitting Electrooptic Filters

Abstract

The objectives of this program are to find and develop new IR transmitting materials and to provide new data on the electrooptic (EO) properties of those most likely to have an EO coefficient an order of magnitude higher than materials currently in development for tunable filters. The main technical problems anticipated include the synthesis and single-crystal growth of these materials: many are poorly characterized and others have high melting points or melt incongruently. Our approach will overcome these obstacles by first synthesizing approximately 20 polycrystalline samples. Subsequently, their dielectric constants at low and ambient temperatures will be determined, and the two best materials of the survey will be grown as single crystals (second year of the program).
