Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

Resource Efficient and Robust RSMA for Visible Light Communications
IEEE Photonics JournalSpectral efficiency (SE) and energy efficiency (EE) are two main metrics for the transmit design in Visible Light Communications (VLC). However, the SE-optimal and EE-optimal strategies may be in conflict with each other to some extent. In this paper, we

A Novel Hybrid Dimming Control Scheme for Visible Light Communications
IEEE Photonics Journal, 2017 A dimming control scheme that combines analog dimming and spatial dimming is proposed. The basic idea of the combined scheme is that both the direct current bias level of each individual light-emitting diode (LED) and the number of glared LEDs are ...
