  • Abstract
    A systematic study was carried out on proton-exchanged LiNbO3 optical waveguides using pyrophosphoric acid. A maximum surface index increase of 0.145 was measured at 0.633 mu m for z-cut substrates. The index profile could be accurately modelled by a polynomial expression of simply by a ´truncated´ step-index profile.
