Abstract
We report on the fabrication and chic((2)) measurements of thin ~10-mum -thick films of periodically poled LiNbO(3), obtained by crystal ion slicing. The d(33) 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(omega, m = 0)-to-TM(omega +omega, 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.
