1. A method for forming a patterned coating on a surface, the method comprising:
- a) reacting a reactant flow to form product particles in a product stream; and
b) directing the product particle stream through a first discrete mask at a surface to form the patterned coating on the surface, the first discrete mask not being bonded to the surface.

Abstract
Three dimensional optical structures are described that can have various integrations between optical devices within and between layers of the optical structure. Optical turning elements can provide optical pathways between layers of optical devices. Methods are described that provide for great versatility on contouring optical materials throughout the optical structure. Various new optical devices are enabled by the improved optical processing approaches.

23. A method for forming at least one coating on a surface with varying composition areas at different locations along the surface, the method comprising:
-
a) reacting a reactant flow to form a product particle stream; and
b) directing the product particle stream at a surface wherein the product particle stream sequentially coats portions of the surface and wherein the product particle stream is altered during the coating process to deposit different product particle compositions at different locations along the surface. - View Dependent Claims (24, 25, 27, 28, 29, 30, 31, 32, 33)
