摘要：
A photoactive medium has a complex format grating written thereon, the complex format grating including at least three component gratings, each of the component gratings characterized by a unique grating vector. Methods for writing the complex format grating include the steps of providing a photoactive medium; and focussing a plurality of pairs of mutually coherent light beams into a focal plane in the medium.
