We have considered the surface
wave formation along the interface of two different media,
charac-terized by the crystal orientation, the strength of
diffusion photorefractive non-linearity (of the gradient type),
and the incident beam amplitude. These spatial waves can be
guided along: PRC`-PRC (PRC is a photorefractive crystal),
PRC - ideal metal and PRC - optically linear dielec-tric
media boundaries; these are used to produce self-induced photorefractive
surface waves, re-sulting from an electromagnetic Eigen-mode
analysis, thus the light self-confinement phenomenon takes
place. Theoretical evidence is given. |
