Abstract

Optical channel waveguides in Nd3+:MgO:LiNbO3 crystals are produced by using implantation of 500 keV protons at dose of 6×1016 ions/cm2 with a stripe photoresist mask. With thermal annealing treatment at 400°C for 60 min, the propagation losses of the waveguides could be reduced down to ∼4 dB/cm at wavelength of 632.8 nm. The calculated modal profiles are in fairly good agreement with the experimental near-field intensity distributions of the waveguide modes. The microluminescence investigation indicates the emission intensity of Nd3+ ions is only slightly modified with respect to the bulk, exhibiting potentials for laser applications.
