The optical transmissivity of a mirrorless, nonlinear, absorbing dielectric thin film is investigated numerically. The dielectric function in the film region is dependent on the intensity of the electromagnetic field. Multivalued solutions of transmissivity as a function of incident power are calculated for the steady-state wave equation. The numerical solution is applied to two different model dielectric functions. As the absorption parameter is increased, larger values of incident intensity are required to switch the systems between stable output states. Also, the peak values of transmissivity are reduced as the absorption is increased.
对无反射、非线性、吸收性介质薄膜的光学透射率进行了数值研究。薄膜区域的介电函数取决于电磁场的强度。针对稳态波动方程，计算了透射率作为入射功率函数的多值解。数值解应用于两种不同的模型介电函数。随着吸收参数的增加，需要更大的入射强度值才能使系统在稳定输出状态之间切换。此外，随着吸收的增加，透射率的峰值会降低。
