Abstract :
The fabrication of optical waveguides in sapphire by the thermal diffusion of titanium is reported. Singlemode operation at λ=633 nm was observed following diffusion at 1950±30°C for up to 3.5 h. Waveguide mode intensity profiles are given and mode depths between 6.2 and 9.6 μm ±1 μm were obtained in the TE polarisation
