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.
