The damage profiles in LiTaO3 induced by H+ ions were investigated using the Rutherford backscattering/channeling technique. We used TRIM (transport of ions in matter) to simulate it. It was found that the shape of the experimental damage profile was similar to one predicted by TRIM'98, but the experimental damage ratio (ND/N) was higher than the calculated damage ratio based on TRIM'98. The modes in LiTaO3 were measured by a prism-coupling method for all samples. The modes were observed only for LiTaO3 implanted with 80, 120, and 150 keV H+ ions. The present result shows that optical wave guides in LiTaO3 can be formed by lower energy H+ ions. |
