A photonic crystal-based broadband graphene saturable absorber
Caoran Shen, Saifeng Zhang, Ivan M. Kislyakov +6
The enhanced nonlinear optical response of a one-dimensional (1D) photonic crystal (PC) made from polymers and graphene composites is observed. The graphene PC was fabricated by sp…
Stimulated Brillouin scattering in dispersed graphene
Ivan M. Kislyakov, Jean-Michel Nunzi, Xiaoyan Zhang +3
We address the problem of the interaction of powerful laser radiation with a transparent substance containing a low concentration of strongly absorbing nanoparticles under the cond…
An all optical phase shifter and switch near 1550nm using tungsten disulfide (WS2) deposited tapered fiber
Kan Wu, Chaoshi Guo, Hao Wang +3
Optical phase shifters and switches play an important role for various optical applications including optical signal processing, sensing and communication. In this paper, we demons…
Giant Two-Photon Absorption in Monolayer MoS2
Yuanxin Li, Ningning Dong, Saifeng Zhang +5
Strong two-photon absorption (TPA) in monolayer MoS2 is demonstrated in contrast to saturable absorption (SA) in multilayer MoS2 under the excitation of femtosecond laser pulses in…
Direct Observationof DegenerateTwo-Photon Absorption and Its Saturation in WS2 and MoS2 Monolayer and Few-Layer Films
Saifeng Zhang, Ningning Dong, Niall McEvoy +10
The optical nonlinearity of WS2, MoS2 monolayer and few-layer films was investigated using the Z-scan technique with femtosecond pulses from the visible to the near infrared. The d…
Optical Limiting and Theoretical Modelling of Layered Transition Metal Dichalcogenide Nanosheets
Ningning Dong, Yuanxin Li, Yanyan Feng +6
Nonlinear optical property of transition metal dichalcogenide (TMDC) nanosheet dispersions, including MoS2, MoSe2, WS2, and WSe2, was performed by using Z-scan technique with ns pu…
WS2 as a saturable absorber for ultrafast photonic applications of mode-locked and Q-switched lasers
Kan Wu, Xiaoyan Zhang, Jun Wang +2
Two-dimensional (2D) nanomaterials, especially the transition metal sulfide semiconductors, have drawn great interests due to their potential applications in viable photonic and op…
