摘要：By coupling few-layer Molybdenum Disulfide (MoS₂) with fiber-taper evanescent light field, a new type of MoS₂ based nonlinear optical modulating element had been successfully fabricated as a two-dimensional layered saturable absorber with strong light-matter interaction. This MoS₂-taper-fiber device is not only capable of passively mode-locking an all-normal-dispersion ytterbium-doped fiber laser and enduring high power laser excitation (up to 1 W), but also functions as a polarization sensitive optical modulating component (that is, different polarized light can induce different nonlinear optical response). Thanks to the combined advantages from the strong nonlinear optical response in MoS₂ together with the sufficiently-long-range interaction between light and MoS₂, this device allows for the generation of high power stable dissipative solitons at 1042.6 nm with pulse duration of 656 ps and a repetition rate of 6.74 MHz at a pump power of 210 mW. Our work may also constitute the first example of MoS₂-enabled wave-guiding photonic device, and potentially give some new insights into two-dimensional layered materials related photonics.
