The excitation of soliton states in optical layers exhibiting Kerr nonlinearities is theoretically investigated. The optical transmission coefficient is obtained as a function of the intensity of an incident light beam. The incident electromagnetic wave is considered to be monochromatic and linearly polarized in the transverse electric configuration. In materials exhibiting self-defocusing nonlinearity, soliton excitations are not observed if the product of the nonlinear dielectric coefficient of the slab and the absolute square of the incident electric-field amplitude is below a well-defined value. At such a limit, a soliton excitation with a position-independent electric field amplitude is observed within the nonlinear layer, regardless of the frequency value of the incident wave.

理论上研究了在表现出克尔非线性的光学层中孤子态的激发。光透射系数是作为入射光束强度的函数获得的。入射电磁波在横向电配置中被认为是单色的和线偏振的。在表现出自散焦非线性的材料中，如果平板的非线性介电系数与入射电场幅度的绝对平方的乘积低于明确定义的值，则不会观察到孤子激发。在这样的限制下，无论入射波的频率值如何，都可以在非线性层内观察到具有与位置无关的电场幅度的孤子激发。
