title: Gradient-index antireflection coatings.
abstract: Thin-film gradient-index profiles have been analyzed and new profiles have been synthesized for broadband antireflection coatings on dielectric surfaces. It is shown that the control of the index gradient as a design parameter can significantly enhance the performance of interference coatings.
