Abstract
A process (400) to construct single- and multi-dimensional optical gratings (100, 800) of interlayers (110, 230, 310 808) of differing refractive index, either in or atop a non-fiber substrate material (104, 202, 302). The optical gratings (100, 800) may particularly be Bragg type gratings, and thus suitable for receiving a laser beam (102, 240, 802) and forming there from one or more reflected beam portions (118, 248, 810) having one or more narrow wavelengths and a passed beam portion (120, 250, 812) of other wavelengths.
