Journal ArticleDOI
Active-Tuning and Polarization-Independent Absorber and Sensor in the Infrared Region Based on the Phase Change Material of Ge 2 Sb 2 Te 5 (GST).
TL;DR: An active absorber with metal-insulator-metal (MIM) scheme with GST in the infrared region with nearly perfect absorbing strategy offers great potential in sensing applications due to its flexibility and polarization-independence.
Journal ArticleDOI
Broadband Achromatic Metalens in the Midinfrared Range
TL;DR: In this article, the Pancharatnam-Berry phase and propagation phase were used to control the wave front of light, from which the chromatic aberration can be eliminated effectively.
Journal ArticleDOI
Efficient Recognition of the Propagated Orbital Angular Momentum Modes in Turbulences With the Convolutional Neural Network
Zikun Wang,Maxime Irene Dedo,Kai Guo,Keya Zhou,Fei Shen,Yongxuan Sun,Shutian Liu,Zhongyi Guo +7 more
TL;DR: In this article, a specially designed six-layer CNN structure in a CPU station was proposed to achieve the recognition of OAM mode in turbulent environment through the feature extraction of the received Laguerre-Gaussian beam's intensity distributions.
Journal ArticleDOI
High-Order Dielectric Metasurfaces for High-Efficiency Polarization Beam Splitters and Optical Vortex Generators.
TL;DR: A high-order dielectric metasurface based on silicon nanobrick array is proposed and investigated, and two polarization beam splitters working in high- order diffraction modes have been designed successfully, which demonstrated a high transmitted efficiency.
Journal ArticleDOI
