ABSTRACT:
An optical element comprising: a first monomer polymerized while in the presence of a second monomer to form a first polymer intermixed with the second monomer, the first polymer having a spatially varying degree of cure that provides a predetermined refractive index profile; and the second monomer polymerized in the presence of the first polymer to form a second polymer intermixed with the first polymer, the second polymer stabilizing the refractive index profile.
