Paper Abstract

Classical broadband antireflection coatings utilize a single halfwave layer to broaden the spectral bandwidth over which antireflection takes place. A logical extension of this design technique is to use multiple halfwave layers to further broaden and/or flatten the spectral response. The generic category of multiple halfwave antireflection coatings are examined. Examples are presented which include both dispersive and non-dispersive calculations. The spectral response of these designs will be compared to a classical quarter-half-quarter antireflection coating. Design characteristics at non-normal incidence are examined as well as sensitivity to errors in thickness, index, and the effects of film inhomogeneity.
