Paper Abstract

Low loss proton-exchanged optical waveguides using phosphoric acid exhibit properties which are different from those using benzoic acid. A maximum surface index increase of 0. 145 was measured for z-cut substrate at O. 633j. m and the index profile could be accurately modelled by a polynomial expression. This paper will review the development of proton-exchanged waveguides and devices using this acid.
