Quasi-BIC laser enabled by high-contrast grating resonator for gas detection
H. Zhang, T. Wang, J. Tian +9
In this work, we propose and numerically investigate a two-dimensional microlaser based on the concept of bound states in the continuum (BIC). The device consists of a thin gain la…
Transverse photon spin beyond interfaces
Liang Peng, Lingfu Duan, Kewen Wang +6
Photons possess spin degree of freedom, corresponding to clockwise and counter clockwise rotating direction of the fields. Photon spin plays an important role in various applicatio…
The scattering of a cylindrical invisibility cloak: reduced parameters and optimization
Liang Peng, Lixin Ran, N. Asger Mortensen
We investigate the scattering of 2D cylindrical invisibility cloaks with simplified constitutive parameters with the assistance of scattering coefficients. We show that the scatter…
Sub-diffraction-limit Observation Realized by Nonlinear Metamaterial Lens
Zhiyu Wang, Yu Luo, Liang Peng +5
In this paper, we show by experiment that by covering a thin flat nonlinear lens on the sources, the sub-diffraction-limit observation can be achieved by measuring either the near-…
Second-Harmonic Generation and Spectrum Modulation by Active Nonlinear Metamaterial
Zhiyu Wang, Yu Luo, Liang Peng +5
The nonlinear properties of a metamaterial sample composed of double-layer metallic patterns and voltage controllable diodes are experimentally investigated. Second harmonics and s…
