HIGHLY NONLINEAR, OPTICAL QUALITY ORGANIC THIN FILMS: ORGANIC VAPOR DEPOSITION

The focus of the proposed program is to introduce a new means for achieving quasi-epitaxial growth which is tailored to the growth of organic films which have large second order, nonlinear optical coefficients. This completely new proposed growth technology builds on a substantial, demonstrated expertise in the vacuum deposition of such nonlinear materials, where the consultant to this SBIR (Prof.S. Forrest, Princeton University) is well-known pioneer in the field of organic thin film growth, and Dr. V.S. Ban, (PI), who is an expert in design of epitaxial reacters and epitaxial growth. We shall apply the new method to the growth of films of DAST, (4-dimethylamino-N-methyl-4-stibazolium tosytale), a material with exceptionally interesting nonlincear optical properties.
