A method for fabricating an optical identification element is provided,
wherein a removable plate or substrate having photosensitive material
fabricated thereon, one or more gratings are written on the
photosensitive material, then lines are etched to create one or more
separate optical identification elements. The one or more gratings may be
written by exposing the photosensitive material to ultraviolet (UV)
light. The lines may be etched to create the one or more separate optical
identification elements by photolithography to define/create the same.
