Role of hot electron scattering in epsilon-near-zero optical nonlinearity

Autor: Wang Heng, Du Kang, Liu Ruibin, Dai Xinhai, Zhang Wending, Chua Soo Jin, Mei Ting

Publikováno v: Nanophotonics, Vol 9, Iss 14, Pp 4287-4293 (2020)

The physical origin of epsilon-near-zero (ENZ) optical nonlinearity lies in the hot-electron dynamics, in which electron scattering plays an important role. With the damping factor defined by hot electron scattering time, the Drude model could be ext

Grating-assisted coupling enhancing plasmonic tip nanofocusing illuminated via radial vector beam

Autor: Lu Fanfan, Zhang Wending, Zhang Jiachen, Liu Min, Zhang Lu, Xue Tianyang, Meng Chao, Gao Feng, Mei Ting, Zhao Jianlin

Publikováno v: Nanophotonics, Vol 8, Iss 12, Pp 2303-2311 (2019)

Tip-enhanced Raman spectroscopy (TERS) is a very useful method to achieve label-free and super-resolution imaging, and the plasmonic tip nanofocusing plays a decisive role for TERS performance. Here, we present a method to enhance the nanofocusing ch

Physical vapor deposition of large-scale PbSe films and its applications in pulsed fiber lasers

Autor: Gao Qun, Yang Hao, Hu Cuichen, He Zhiwen, Lu Hua, Zhang Wending, Mao Dong, Mei Ting, Zhao Jianlin

Publikováno v: Nanophotonics, Vol 9, Iss 8, Pp 2367-2375 (2019)

Lead selenide (PbSe) is a new emerging semiconductor with layer-dependent bandgap that has attracted much interest due to its high infrared response and good environmental stability. We have prepared large-scale PbSe films with the area of 7 cm2 and

Highly efficient plasmonic nanofocusing on a metallized fiber tip with internal illumination of the radial vector mode using an acousto-optic coupling approach

Autor: Liu Min, Lu Fanfan, Zhang Wending, Huang Ligang, Liang Shuhai, Mao Dong, Gao Feng, Mei Ting, Zhao Jianlin

Publikováno v: Nanophotonics, Vol 8, Iss 5, Pp 921-929 (2019)

Tip-based plasmonic nanofocusing, which delivers light into a nanoscale region and achieves localized electromagnetic (EM) field enhancement beyond the diffraction limit, is highly desired for light-matter interaction-based super-resolution imaging.

Mode evolution and nanofocusing of grating-coupled surface plasmon polaritons on metallic tip

Autor: Lu Fanfan, Zhang Wending, Huang Ligang, Liang Shuhai, Mao Dong, Gao Feng, Mei Ting, Zhao Jianlin

Publikováno v: Opto-Electronic Advances, Vol 1, Iss 6, Pp 180010-1-180010-7 (2018)

We present a detailed analysis on mode evolution of grating-coupled surface plasmonic polaritons (SPPs) on a conical metal tip based on the guided-wave theory. The eigenvalue equations for SPPs modes are discussed, revealing that cylindrical metal wa
