We reported on the generation of dissipative rogue waves (DRWs) induced by long-range chaotic multi-pulse interactions in a fiber laser based on a topological insulator (TI)-deposited microfiber photonic device. By virtue of the simultaneous saturable absorption effect and high nonlinearity provided by the TI-deposited microfiber, a localized, chaotic multi-pulse wave packet with strong long-range nonlinear interactions could be obtained, which gives rise to the formation of DRWs. The results might enhance the understanding of DRWs in optical systems, and further demonstrated that the TI-deposited microfiber could be considered as an excellent photonic device with both saturable absorption and highly nonlinear effects for the application field of nonlinear optics.
我们报道了基于拓扑绝缘体（TI）沉积微光纤光子器件的光纤激光器中，由长程混沌多脉冲相互作用诱导产生的耗散 rogue 波（DRW）。借助 TI 沉积微光纤提供的同时饱和吸收效应和高非线性，可获得具有强长程非线性相互作用的局域化混沌多脉冲波包，这导致了 DRW 的形成。这些结果可能会增进对光学系统中 DRW 的理解，并进一步证明 TI 沉积微光纤可被视为一种出色的光子器件，在非线性光学应用领域兼具饱和吸收和高度非线性效应。
