摘要 通过理论模拟,研究了稳态条件下,基于偶氮苯光致异构的饱和吸收效应的光学双稳态性质。首先计算了在饱和吸收条件下样品的透射率随入射光强的变化关系,然后计算在饱和吸收条件下光学双稳态过程。结果表明,在稳态条件下,基于偶氮苯的光致异构过程能够实现光学双稳态的开关过程,光学双稳态开关过程主要受以下3个因数影响:①样品的温度(用K参数表示),研究表明偶氮苯稳态条件下开关过程随K值的增大而明显增强;②反式偶氮苯分子的吸收截面σT,双稳态开关过程随σT的增加而增强;③顺式偶氮苯分子的吸收截面σC,开关过程随σC的增加而减弱。 A theoretical study of the steady mirorless optical bistability,based on the photoisomerization of azobenzene,was reports.Firstly, the transmissions due to the saturated absorption of azobenzene molecules have been calculated. Then, the mirrorless optical bistability processes have been calculated under different absorption cross_sections σ_T and σ_C for trans and cis azobenzene molecules respectively.Finally,the thermal constant K and its influence on the optical bistability has been discussed.
