Published in 2022 at "Advanced Materials"

DOI: 10.1002/adma.202201229

Abstract: The direct photocurrent detection capability of light orbital angular momentum (OAM) has recently been realized with topological Weyl semimetals, but it is limited to the near‐infrared wavelength range. The extension of the direct OAM detection… read more here.

Published in 2018 at "Optik"

DOI: 10.1016/j.ijleo.2017.10.144

Abstract: We generalize the concept of perfect optical vortices, studying the elliptic perfect optical vortices (EPOVs), which also have diameters independent on the topological charge. A pure-phase diffractive optical element is proposed for efficient generation of… read more here.

Published in 2020 at "Electromagnetics"

DOI: 10.1080/02726343.2020.1780378

Abstract: ABSTRACT As the traditional resources (such as frequency, time, and space) are efficiently utilized, it becomes more and more challenging to satisfy the ever-lasting, capacity-growing, and users-boosting demand for wireless networks. Recently, the orthogonal Orbital… read more here.
