Abstract

Magnesium-doped lithium niobate has been shown to be persistent to substantially higher optical power¹ than undoped material. It is, therefore, expected to be favorable as substrate material for titanium-diffused waveguides used for frequency conversion. It has been reported that the titanium diffusivity is different in doped and undoped material.^2,3 Available information on diffusion properties is, however, limited and partly contradictory, and to our knowledge there are no diffusion data published for channel guides.
