基于双光子光折变效应的Manakov光伏孤子温度特性

基于具有双光子光伏光折变效应的介质，数值研究了双光子Manakov光伏孤子的温度特性。结果表明：在室温范围内，亮-亮、暗-暗和亮-暗Manakov光伏孤子对成分的峰值光强和半峰全宽均受温度影响。亮-亮Manakov光伏孤子对的强度包络随着晶体温度的升高，其两孤子成分的峰值光强都逐渐减小，而其半峰全宽逐渐增加。暗-暗和亮-暗Manakov光伏孤子对具有类似的温度特性。在一定的温度范围内，两孤子成分可以克服温度扰动而演化为稳定孤波。

Temperature characteristics of Manakov photovoltaic solitons based on two-photon photorefractive effect

Temperature characteristics of Manakov photovoltaic solitons in two-photon photovoltaic photorefractive crystal were investigated by numerical methods. The results show that the peak intensities and the full width of half maximum (FWHM) of two components of the bright-bright, dark-dark and bright-dark Manakov photovoltaic solitons are related to temperature. When the temperature of crystal increases, the peak intensities of two components of the bright-bright Manakov photovoltaic soiltons will decrease and the full width of half maximum of two components  increase. The dark-dark and bright-dark Manakov photovoltaic solitons have the same temperature characteristics as the bright-bright Manakov photovoltaic solitons. Moreover, two components of the Manakov solitons will evolve into stable solitary waves by overcoming the less perturbation in a certain range of temperature.
