Patent number: 6641743Abstract: A method for forming waveguides in an optical material such as lithium niobate comprises the steps of providing an exchange agent including a proton-supplying medium and a catalyst, and exposing a selected portion of the optical material to the exchange agent for a predetermined time and at a predetermined temperature. Preferably, the catalyst is a metallic cation having a valence of at least +2, and the proton-supplying medium is a weak acid with a pKa of greater than about 4.5 or a lithium-buffered (“starved”) acidic solution. The catalyst accelerates the rate at which protons are exchanged with corresponding ions in the optical material lattice, thereby reducing the time required to produce a waveguide in the exposed portion of the optical material.Type: GrantFiled: June 19, 2001Date of Patent: November 4, 2003Inventors: Mark L.
