Optical characteristics of light waves in two-dimensional random media with uniaxial scatterers

Liu Hai¹, Zhang Xiangjun¹, Ren Zihui¹, Lü Jiantao²

A new model was built for the research on two-dimensional anisotropic random medium, and the dielectric constant distribution was precisely described. The optical property of the light waves in two-dimensional random media with uniaxial scattering particles investigated by simultaneously solving Maxwell’s equations and rate equations of electronic population. Results show that ordered scatterers in anisotropic material can also form localization of light-waves if the index of refraction of the uniaxial scatterers distribute randomly in two-dimensional media. The randomness of the rotation angle of the optic axis determines the index of refraction of each scattering particle and reinforces the random lasing in random media. The results are very helpful for the development of new anisotropic random material.

Abstract:

A new model was built for the research on two-dimensional anisotropic random medium, and the dielectric constant distribution was precisely described.

Results show that ordered scatterers in anisotropic material can also form localization of light-waves if the index of refraction of the uniaxial scatterers distribute randomly in two-dimensional media. The randomness of the rotation angle of the optic axis determines the index of refraction of each scattering particle and reinforces the random lasing in random media. The results are very helpful for the development of new anisotropic random material.
