从理论上研究了自相似波纹光学非线性波导的光谱传输特性。该结构可以通过具有引导膜厚度的方波调制的平面波导来实现，使得最厚的层属于三元康托集。线性结构的透射谱在禁带间隙内呈现出局部峰值。在接近线性传输光谱中出现的局部深峰的波长下研究结构的非线性传输行为。发现了双稳态行为，并与非线性布拉格反射器装置和集成非线性多层法布里-珀罗谐振器进行了比较。
The spectral transmission properties of a self-similar corrugated optical nonlinear waveguide are studied theoretically. The structure can be realized by a planar waveguide with a square-wave modulation of the guiding film thickness such that the thickest layers belong to a triadic Cantor set. The transmission spectrum of the linear structure exhibits localized peaks inside forbidden frequency band gaps. The nonlinear transmission behavior of the structure is studied at wavelengths close to localized deep peaks that appear in the linear transmission spectrum. Bistable behavior is found, and a comparison with nonlinear Bragg reflector devices and with an integrated nonlinear multilayer Fabry–Perot resonator.
