Gawith, C.B.E., Shepherd, D.P., Abernethy, J.A., Hanna, D.C., Ross, G.W. and Smith, P.G.R. (1999) Second-harmonic generation in a direct-bonded periodically-poled-LiNbO3 buried waveguide. Optics Letters, 24, (7), 481-483. (doi:10.1364/OL.24.000481).
We report the fabrication of a 12-µm-thick periodically poled LiNbO3 planar waveguide buried in LiTaO3 by direct bonding of precision-polished surfaces. Frequency doubling of the 1064-nm output of a cw diode-pumped Nd:YAG laser was performed in a 5.5-mm-long device with a 6.50-µm-period grating at an elevated temperature of 174 °C. The resultant green second-harmonic output exhibited fundamental-spatial-mode characteristics at a 4.3% %/W conversion efficiency.
