Journal ArticleDOI
Functional inks and printing of two-dimensional materials.
Guohua Hu,Joohoon Kang,Leonard W. T. Ng,Xiaoxi Zhu,Richard C. T. Howe,Christopher G. Jones,Mark C. Hersam,Tawfique Hasan +7 more
TL;DR: In this review, the current progress on ink formulation of two-dimensional materials and the printable applications enabled by them are summarized and perspectives on their research and technological future prospects are presented.
Journal ArticleDOI
Tunable Q-switched fiber laser based on saturable edge-state absorption in few-layer molybdenum disulfide (MoS₂).
Robert I. Woodward,E. J. R. Kelleher,Richard C. T. Howe,Guohua Hu,Felice Torrisi,Tawfique Hasan,Sergei Popov,James Taylor +7 more
TL;DR: A mechanism, based on edge states within the bandgap, is proposed, responsible for the wideband nonlinear optical absorption exhibited by the few-layer MoS₂ sample, despite operating at photon energies lower than the material bandgap.
Journal ArticleDOI

TL;DR: A stable black phosphorus ink suitable for printed ultrafast lasers and photodetectors is demonstrated, enabling scalable development of optoelectronic and photonic devices.
Journal ArticleDOI
Solution processed MoS2-PVA composite for sub-bandgap mode-locking of a wideband tunable ultrafast er:fiber laser
Meng Zhang,Richard C. T. Howe,Robert I. Woodward,Edmund J. R. Kelleher,Felice Torrisi,Guohua Hu,Sergei Popov,J. Roy Taylor,Tawfique Hasan +8 more
TL;DR: In this paper, a few-layer molybdenum disulfide (MoS2)-polymer composite by liquid phase exfoliation of chemically pristine MoS2 crystals is used to demonstrate a wideband tunable, ultrafast mode-locked fiber laser.
Journal ArticleDOI
Wideband saturable absorption in few-layer molybdenum diselenide (MoSe 2 ) for Q-switching Yb-, Er- and Tm-doped fiber lasers
Robert I. Woodward,Richard C. T. Howe,T. H. Runcorn,Guohua Hu,Felice Torrisi,E. J. R. Kelleher,Tawfique Hasan +6 more
TL;DR: In this paper, a free-standing molybdenum diselenide (MoSe2) saturable absorber was fabricated by embedding liquid-phase exfoliated few-layer MoSe2 flakes into a polymer film, which is used to Q-switch fiber lasers based on ytterbium (Yb), erbium(Er) and thulium (Tm) gain fiber, producing trains of microsecond-duration pulses with kilohertz repetition rates at 1060 nm, 1566 nm and 1924 nm, respectively.
