Efficient refinement of inhomogeneous optical coatings: synthesis by simultaneous thickness and refractive-index optimization

A thin film synthesis technique based on the refinement of inhomogeneous systems is improved by the implementation of simultaneous refractive index and thickness optimization. Severe artifacts generated at oblique incidence by an earlier version of the method are eliminated. Complex designs comparable to published solutions synthesized with the Needle Method are demonstrated.NRC publication: Ye
