| Abstract: | We provide a theoretical investigation of effects of the temperature on the steady-state bright solitons in centrosymmetric
photorefractive crystals. Three physical factors related to the effects of the temperature, i.e., the dielectric constant,
diffusion process and dark irradiance, are considered. Our results show that both the intensity profile and self-deflection
of solitons strongly depend on the crystal temperature and the dielectric constant temperature dependence dominates the process. |
