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.

Infrared Colloidal Quantum Dot Edge Emitting Lasers Integrated on Silicon
Advanced Optical Materials, EarlyView.In this work, the first monolithic integration of Pb‐chalcogenide CQDs in an edge‐emitting DFB laser cavity onto a Si/SiO2 substrate has been demonstrated. The optimizations of SiO2 layer thickness, engineering of the grating duty cycle, and implementing λ/4 phase shift resulted in the achievement of spectrally pure, single‐mode lasing at 1650 nm with ...
