Abstract: An optical element includes a transmissive layer arranged on a substrate and made up of discrete volumes of first and second optical media. The layer is between the substrate and another optical medium. The volumes are arranged so that, averaged over a wavelength's distance of an incident optical signal, the effective reflectivities of the two surfaces of the transmissive layer and the effective double-pass phase delay through the transmissive layer are substantially constant across the transmissive layer. The reflectivities and phase delay result in net power reflectivity that differs from that of the substrate in direct contact with the other optical medium. The transmissive layer can be arranged as an anti-reflection layer.
