| Abstract: | In a biased dissipative photovoltaic--photorefractive system, thispaper investigates the temperature effect on the evolution and theself-deflection of the dissipative holographicscreening-photovoltaic (DHSP) solitons. The results reveal that, theevolution and the self-deflection of the bright and dark DHSPsolitons are influenced by the system temperature. At a giventemperature, for a stable DHSP soliton originally formed in thedissipative system, it attempts to evolve into another DHSP solitonwhen the temperature change is appropriately small, whereas it willbecome unstable or break down if the temperature departure is largeenough. Moreover, the self-deflection degree of the solitary beamcentre increases as temperature rises in some range, while it isdecided by the system parameters and is slight under small-signalcondition. The system temperature can be adjusted to change theformation and the self-deflection of the solitary beam in order togain certain optical ends. In a word, the system temperature plays arole for the DHSP solitons in the dissipative system. |
