Abstract
We report on the fabrication and χc(2) measurements of thin ∼10-μm -thick films of periodically poled LiNbO3, obtained by crystal ion slicing. The d33 optical coefficient in the films is probed by sum-frequency generation with a short-pulse laser source at 1550 nm and compared with that of the bulk. Efficient, room-temperature TM(ω, m = 0)-to-TM(ω +ω, m = 0) mode conversion is obtained in the films. These measurements show that domain periodicity is preserved during ion implantation and that the thin films have bulklike nonlinearity and material dispersion.
