Abstract
A method for coupling fibres to Ti-diffused waveguides in LiNbO3 is described, by which ion-milled grooves in the LiNbO3 substrate are used to locate the fibres. The coupling loss is analysed, and fabrication parameters optimised to minimise insertion loss due to modal mismatch. A net insertion loss of ¿2.6 dB has been measured for the coupler.
