摘要
METHOD FOR PRODUCING waveguides FOR ORDINARY Refractive Index lithium niobate by double ion exchange. WITH A DEEP first exchange proton is generated MULTIPLE LAYER micras WHICH SOME removed a FRACTION MATERIAL OF LITHIUM ION GENERATING A DECREASE IN ORDINARY INDEX APPROXIMATELY DlNO _ 0.04 (FIG. 1). A second shallower than first exchange, solution RICH IN LITHIUM, re-introduced lithium ions AND RECOVER THE INDEX APPROXIMATELY ORDINARY to its initial value in a layer less than the first. This layer ALONG WITH THE REST OF THE ABOVE CAPA makes SUSTRATO CASH IS Waveguide (FIG. 2). Waveguide FINALLY HAVE A REGULAR INDEX JUMP FOR DlNO 0.03 = 0.6328 MIM.
