Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors

Advanced Optical Materials, Volume 14, Issue 3, 19 January 2026.
Group delay dispersion of novel semiconductor‐based optics is measured in the mid‐infrared spectral range (2.5 to 4.8 μm$\rm \umu{\rm m}$). Comparisons are made between simulations, measurements conducted with a home‐built white light interferometer, and measurements performed with a commercially available FTIR.

A Near Infrared Emission Feature from Visible Fluorescence Tails and its Correlation with Singlet Oxygen

Advanced Optical Materials, Volume 14, Issue 2, 14 January 2026.
A persistant NIR emission tail and feature at 923 nm is observed during photochemical singlet oxygen generation using various photosensitizers. While initially considered as singlet oxygen phosphorescence we show that it arises from the NIR‐tail of (visible) photosensitizer emission and the non‐linear increase of detector sensitivity.

Uniaxial stress flips the natural quantization axis of a quantum dot for integrated quantum photonics

Nature Communications, 2018
The natural quantization axis in quantum dots, which is usually parallel to the growth direction, is not ideal for planar photonic circuits. Here Yuan et al.

Boosting the Performance of Epitaxial Perovskite Microstructures by Surface Passivation

Advanced Optical Materials, Volume 14, Issue 1, 9 January 2026.
Surface passivation is applied to epitaxial perovskite structures. Improvements are obtained in respect to luminescence intensity and decay time, as well in respect to photodetection and lasing. Highlight results include photoluminescence transients that are limited only by carrier diffusion and a record low laser threshold for microcrystal‐based ...
