论文摘要
我们在弹性聚合物波导阵列中采用Su-Schrieffer-Heeger模型来设计并实现行进的拓扑保护模式。观察到的静脉缺陷速度的光场的离域化与理论描述非常吻合。我们应用机械应变来调节晶格的耦合系数。这项工作展示了一个新型平台,用于快速对拓扑光子设备进行快速原型制作,并将应变调整作为拓扑波导阵列的可行设计参数。
We employ the Su-Schrieffer-Heeger model in elastic polymer waveguide arrays to design and realize travelling topologically protected modes. The observed delocalization of the optical field for superluminal defect velocities agrees well with theoretical descriptions. We apply mechanical strain to modulate the lattices' coupling coefficient. This work demonstrates a novel platform for rapid prototyping of topological photonic devices and establishes strain-tuning as a viable design parameter for topological waveguide arrays.
