Abstract
A tunable interferometer for creating an interference pattern of variable periodicity at a fixed location is disclosed. The interferometer includes an optical element for splitting an input beam into a first write beam and a second write beam which are parallel to one another and have a variable distance therebetween. The interferometer also includes a beam directing element for receiving the parallel first and second write beams to intersect at the fixed location with an angle of intersection which is a function of the variable distance between the parallel first and second write beams received.
