Paper Abstract

The NRCC Fourier transform synthesis method has been applied for the first time to an optical thin film design problem in which the external media are different. Graded index AR coatings for germanium substrates have been synthesized and compared to multilayer solutions. No limits have been imposed on the refractive indices. Although such systems cannot be put into practice, they provide basic insight into the general nature of broadband AR coatings. Admittance diagrams have been calculated for some of the systems to gain further understanding of their behavior.
