Abstract
A method of fabricating an optical element, comprises fabricating a three-dimensional mold having a relief pattern complementary to a pattern of the optical element to be fabricated, contacting the relief pattern with a solidifiable transmissive material, and solidifying the material thereby forming a transmissive substrate having the pattern thereupon. The method also comprises contacting the transmissive substrate with one or more substances wherein a difference in refractive indices between the substance(s) and the transmissive substrate is less than about 0.1.
