我们报告了光学克尔效应在多层介质涂层中的应用，以前只在理论上讨论过。我们提出了具有层特异性克尔非线性的多层介质光学结构的设计和实现，该结构允许剪裁强度依赖效应。所演示的介质非线性多层涂层的反射率调制深度可达6%。我们发现非线性是基于光学克尔效应，其恢复时间比激光脉冲包络线快1 ps。由于设计的高度灵活性，所报道的介电非线性多层涂层有可能在非线性光学和超快激光应用中开辟迄今为止前所未有的可能性。
We report the utilization of the optical Kerr effect in multilayer dielectric coatings, previously discussed only theoretically. We present the design and realization of multilayer dielectric optical structures with layer-specific Kerr nonlinearities, which permit tailoring of the intensity-dependent effects. The modulation depth in reflectance reaches up to 6% for the demonstrated examples of dielectric nonlinear multilayer coatings. We show that the nonlinearity is based on the optical Kerr effect, with the recovery time faster than the laser pulse envelope of 1 ps. Due to high flexibility in design, the reported dielectric nonlinear multilayer coatings have the potential to open hitherto unprecedented possibilities in nonlinear optics and ultrafast laser applications.
