Gallium-diffused waveguides in sapphire
The fabrication and characterisation of gallium-diffused planar waveguides in sapphire is reported. Waveguides were fabricated by diffusion of 60nm - 200nm thick films of gallium oxide into c-cut sapphire at 1600°C for times ranging between 6 and 16 hours. Near-field intensity profiles of the guided...
