Mechanism of self-organised light-induced scattering in periodically poled lithium niobate
Sturman, B., Aguilar, M., Agulló-López, F., Pruneri, V., Kazansky, P.G. and Hanna, D.C. (1996) Mechanism of self-organised light-induced scattering in periodically poled lithium niobate. Applied Physics Letters, 69, (10), 1349-1351. (doi:10.1063/1.117432).
It is shown that the photorefractive grating produced by a pair of plane waves in periodically poled lithium niobate includes an additional set of spatial harmonics related to the periodic domain structure. This results in new schemes for photorefractive wave coupling. Using the modified phase matching conditions and the concept of optical oscillation we accurately describe the position of the diffraction peaks and explain the main characteristics of self-organized photoinduced scanning reported recently.
