Abstract: | In a biased dissipative photovoltaic--photorefractive system, this
paper investigates the temperature effect on the evolution and the
self-deflection of the dissipative holographic
screening-photovoltaic (DHSP) solitons. The results reveal that, the
evolution and the self-deflection of the bright and dark DHSP
solitons are influenced by the system temperature. At a given
temperature, for a stable DHSP soliton originally formed in the
dissipative system, it attempts to evolve into another DHSP soliton
when the temperature change is appropriately small, whereas it will
become unstable or break down if the temperature departure is large
enough. Moreover, the self-deflection degree of the solitary beam
centre increases as temperature rises in some range, while it is
decided by the system parameters and is slight under small-signal
condition. The system temperature can be adjusted to change the
formation and the self-deflection of the solitary beam in order to
gain certain optical ends. In a word, the system temperature plays a
role for the DHSP solitons in the dissipative system. |
