ABSTRACT:
A method of producing a buried long period grating which is substantially unaffected by material stability, high tolerance requirements, stringent machining requirements, and heat transfer. The method takes a plurality of rectangular-shaped pieces of dielectric material and by a series of appropriate cuts, coatings and attachments produces an effective buried long period grating.
