Efficient supercontinuum generation demands for fine‐tuning of the dispersion of the underlying waveguide. Resonances introduced into waveguide systems can substantially improve nonlinear dynamics in ultrafast supercontinuum generation via modal hybridization and formation of avoided crossings. Using the example of exposed core fibers functionalized by nanofilms with sub‐nanometer precision both zero‐dispersion and dispersive wave emission wavelengths are shifted by 227 and 300 nm, respectively, at tuning slopes higher than 20 nm/nm. The presented concept relies on dispersion management via induced resonances and can be straightforwardly extended to other deposition techniques and film geometries such as multilayers or 2D materials. It allows for the creation of unique dispersion landscapes, thus tailoring nonlinear dynamics and emission wavelengths and for making otherwise unsuitable waveguides relevant for ultrafast nonlinear photonics.

共振诱发的色散调整，通过裸露的芯纤维中的纳米膜来调整非孤子辐射。

高效的超连续谱产生要求对下层波导的色散进行微调。通过模态杂交和避免交叉的形成，引入波导系统的共振可以大大改善超快超连续谱产生中的非线性动力学。以被亚纳米级精度的纳米膜功能化的裸露芯纤维为例，零色散和色散波发射波长在调谐斜率大于20 nm / nm时分别偏移了227和300 nm。提出的概念依赖于通过感应共振进行的色散管理，可以直接扩展到其他沉积技术和膜几何形状，例如多层或2D材料。它允许创建独特的分散景观，
