  • Abstract
    A new fibre-Ti: LiNbO3 waveguide coupling loss reduction method, which symmetrises the waveguide depth index profile by Mg diffusion after Ti-diffused waveguide formation, is proposed. A fibre-to-fibre total insertion loss of 0.5 dB for a 1 cm-long waveguide has been obtained using this method.
