文摘

We report on the green up-conversion emission from Er³⁺, MgO codoped nearly stoichiometric LiNbO₃ planar waveguides fabricated by the swift C⁵⁺ ion irradiation. The characteristics of the waveguides are investigated by using a continuous wave laser at wavelength of 800 nm. The reconstructed distribution of the refractive index of the C ion irradiated waveguides shows a 鈥渂arrier and well鈥?profile. The up-conversion emissions of green light, corresponding to the transition of and bands, have been observed in the waveguides with intensity of 40% of that from the bulk.
