TL;DR: The operation of a broadband MoS2 saturable absorber is demonstrated by the introduction of suitable defects and it is believed that the results provide some inspiration in the investigation of two-dimensional optoelectronic materials.

TL;DR: Based on the easy manipulation, low cost, large scale, and broadband photoresponse, this present detector has significant potential for the applications in optoelectronics and electronics in the future.

TL;DR: Passively Q-switched nanosecond pulsed erbium-doped fiber laser based on MoS(2) saturable absorber (SA) is experimentally demonstrated and the experimental results further verify that MoS (2) possesses the potential advantage for stable Q- Switched pulse generation at 1.5 μm.

TL;DR: The fabrication of a visible optical modulator and pulsed visible lasers based on atomic-layer molybdenum sulfide (MoS2), a ultrathin two-dimensional material with about 9–10 layers is demonstrated and the theoretical prediction for the low-dimensional optoelectronic modulating devices in the visible wavelength region is verified.

TL;DR: In this paper, the authors investigated the mechanisms of SA and RSA in Au NPs and found that high-order nonlinearities play a vital role in the change of the nonlinear absorption behavior from SA to RSA.
