Abstract
A method for fabricating an angled diffraction grating (12) is provided. An optical medium (13) with fine lines and spaces that are defined in an etch mask is provided. Transferring the defined lines and spaces of the etch mask into the optical medium (13) at a desirable angle is achieved by an etching means, thereby resulting in an angled diffraction grating (12).
