Journal ArticleDOI
Ultrafast Saturable Absorption of Two-Dimensional MoS2 Nanosheets
Kangpeng Wang,Jun Wang,Jintai Fan,Mustafa Lotya,Arlene O’Neill,Daniel Fox,Yanyan Feng,Xiaoyan Zhang,Benxue Jiang,Quanzhong Zhao,Hongzhou Zhang,Jonathan N. Coleman,Long Zhang,Werner J. Blau,Werner J. Blau +14 more
TL;DR: Employing high-yield production of layered materials by liquid-phase exfoliation, molybdenum disulfide (MoS2) dispersions with large populations of single and few layers were prepared and exhibited significant saturable absorption (SA) for the femtosecond pulses.
Journal ArticleDOI
Broadband ultrafast nonlinear absorption and nonlinear refraction of layered molybdenum dichalcogenide semiconductors
Kangpeng Wang,Kangpeng Wang,Yanyan Feng,Chunxia Chang,Jingxin Zhan,Chengwei Wang,Quanzhong Zhao,Jonathan N. Coleman,Long Zhang,Werner J. Blau,Werner J. Blau,Jun Wang +11 more
TL;DR: The versatile ultrafast nonlinear properties imply a huge potential of the layered MoX2 semiconductors in the development of nanophotonic devices, such as mode-lockers, Optical limiters, optical switches, etc.
Journal ArticleDOI
Direct Observation of Degenerate Two-Photon Absorption and Its Saturation in WS2 and MoS2 Monolayer and Few-Layer Films.
Saifeng Zhang,Ningning Dong,Niall McEvoy,Maria O'Brien,Sinéad Winters,Nina C. Berner,Chanyoung Yim,Yuanxin Li,Xiaoyan Zhang,Zhanghai Chen,Long Zhang,Georg S. Duesberg,Jun Wang +12 more
TL;DR: The giant nonlinearity of WS2 and MoS2 films is attributed to a two-dimensional confinement, a giant exciton effect, and the band edge resonance of TPA.
Journal ArticleDOI
Ultrafast Nonlinear Excitation Dynamics of Black Phosphorus Nanosheets from Visible to Mid-Infrared
Kangpeng Wang,Beata M. Szydłowska,Gaozhong Wang,Xiaoyan Zhang,Jing Jing Wang,John J. Magan,Long Zhang,Jonathan N. Coleman,Jun Wang,Werner J. Blau +9 more
TL;DR: In a comparative study with graphene, it is found that black phosphorus has a faster carrier relaxation in near- and mid-infrared region and black phosphorus is also confirmed to be better as saturable absorber to MoS2 in infrared region.
Journal ArticleDOI
Single-Mode Lasers Based on Cesium Lead Halide Perovskite Submicron Spheres.
Bing Tang,Hongxing Dong,Liaoxin Sun,Weihao Zheng,Qi Wang,Fangfang Sun,Xiongwei Jiang,Anlian Pan,Long Zhang,Long Zhang +9 more
TL;DR: This work illustrates that the well-controlled synthesis of metal cesium lead halide perovskite nano/microspheres may offer an alternative route to produce a widely tunable and greatly miniaturized single-mode laser.
