Helmut Schmidt, Herbert Krug, Peter W Oliveira, Stefan Sepeur: Optical components with a graded-index structure, and method of manufacturing such components. Institut für Neue Materialien gemeinnützige, Heller Erhman White & McAuliffe, May 22, 2001: US06236493 (45 worldwide citation)

Optical components have a material-distribution gradient due to nanometer-size particles embedded in a solid matrix. The components are manufactured by forming a dispersion of nanometer-size particles in a liquid, curable matrix material, causing the particles to migrate in the matrix material on th ...
