Two-dimensional (2D) materials have emerged as attractive mediums for fabricating versatile optoelectronic devices. Recently, few-layer molybdenum disulfide (MoS₂), as a shining 2D material, has been discovered to possess both the saturable absorption effect and large nonlinear refractive index. Herein, taking advantage of the unique nonlinear optical properties of MoS₂, we fabricated a highly nonlinear saturable absorption photonic device by depositing the few-layer MoS₂ onto the microfiber. With the proposed MoS₂ photonic device, apart from the conventional soliton patterns, the mode-locked pulses could be shaped into some new soliton patterns, namely, multiple soliton molecules, localized chaotic multipulses, and double-scale soliton clusters. Our findings indicate that the few-layer MoS₂-deposited microfiber could operate as a promising highlynonlinear photonic device for the related nonlinear optics applications.
