基于液晶折射率对温度和电场的特性,采用传输矩阵法,研究了含一缺陷层一维液晶填充光子晶体缺陷模电场和温度调控特性。研究结果表明:当温度T在273～330 K内一定时,随着垂直入射光与电场方向间夹角θ在(0,π/2)内增大,缺陷模波长向短波方向漂移,最大调控波长为37.3 nm。当夹角θ在(0,π/2)内一定时,随着外界温度T在273～330 K内升高,缺陷模波长发生改变,变化量先负后正,最大调控波长为21.9 nm。当θ=0.7505时,不管外界温度T在273～330 K内如何变化,缺陷模波长保持不变。温度对缺陷模波长的影响比垂直入射光与电场方向间夹角θ对缺陷模波长的影响更弱。
Based on the properties of liquid crystal refractive index on temperature and electric field, the transfer matrix method was used to study the mode electric field and temperature control characteristics of one-dimensional liquid crystal filled photonic crystal defects with one defect layer. The results show that when the temperature T is constant from 273 K to 330 K, the defect mode wavelength shifts to the shortwave direction as the angle θ between the perpendicular incident light and the electric field increases within (0, π / 2) The wavelength is 37.3 nm. When the included angle θ is constant within (0, π / 2), the defect mode wavelength changes with the increase of the external temperature T within 273 ~ 330 K, and the maximum variation is 21.9 nm. When θ = 0.7505, no matter how the outside temperature T changes within 273 ~ 330 K, the defect mode wavelength remains unchanged. The influence of temperature on the wavelength of the defect mode is weaker than the angle θ between the normal incidence direction and the field direction on the defect mode wavelength.
