Primarily isotropic nature of photorefractive screening solitons and the interactions between them |
|
| Authors: | Meng H Salamo G Segev M |
| Abstract: | We present experimental evidence demonstrating that the photorefractive-index change responsible for the formation of photorefractive spatial screening solitons and coherent collisions between them is primarily isotropic in nature, even though the photorefractive medium is inherently anisotropic. |
