ABSTRACT:
A method for controlled fabrication of a waveguide region in a crystalline member, such as lithium niobate. The crystalline member is placed within a crucible which gives off the same metal component as the crystalline member at a predetermined temperature. Both the crystalline member and the crucible are heated in a controlled highly oxidizing atmosphere. During fabrication of the waveguide region, this atmosphere enhances oxidation of optical damage inducing impurities in the crystalline member. Waveguides so fabricated resist the development of laser induced optical damage.
