Abstract
A method for making a photonic structure, including creating a first vapor stream of a first vapor material, the first vapor stream having a first non-uniform flux in at least one direction; and moving a substrate in at least a portion of the vapor stream. In addition, the method includes depositing the first vapor material on a first major surface of said substrate, and forming a first layer and a density gradient in the first layer during deposition. The first layer is disposed on and the density gradient is in a direction perpendicular to the first major surface.
