Generation and modulation of multiple 2D bulk photovoltaic effects in space-time reversal asymmetric 2H-FeCl2
Liang Liu, Xiaolin Li, Luping Du +1
The two-dimensional (2D) bulk photovoltaic effect (BPVE) is a cornerstone for future highly efficient 2D solar cells and optoelectronics. The ferromagnetic semiconductor 2H-FeCl2 i…
Deep-subwavelength features of photonic skyrmions in a confined electromagnetic field with orbital angular momentum
Luping Du, Aiping Yang, Anatoly V. Zayats +1
In magnetic materials, skyrmions are nanoscale regions where the orientation of electron spin changes in a vortex-type manner. Here we show that spin-orbit coupling in a focused ve…
Design of optimal illumination patterns in single-pixel imaging using image dictionaries
Jun Feng, Shuming Jiao, Yang Gao +2
Single-pixel imaging (SPI) has a major drawback that many sequential illuminations are required for capturing one single image with long acquisition time. Basis illumination patter…
Diffraction-Free Bloch Surface Waves
Ruxue Wang, Yong Wang, Douguo Zhang +11
In this letter, we demonstrate a novel diffraction-free Bloch surface wave (DF-BSW) sustained on all-dielectric multilayers that does not diffract after being passed through three…
Ultra-broadband On-chip Twisted Light Emitter
Zhenwei Xie, Ting Lei, Fan Li +7
On-chip twisted light emitters are essential components for orbital angular momentum (OAM) communication devices, which could address the growing demand for high-capacity communica…
