Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors

open access: yesAdvanced Optical Materials, EarlyView.
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

open access: yesAdvanced Optical Materials, EarlyView.
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.

Quantum Emission in Monolayer WSe2 Transferred onto InP Nanowires

open access: yesAdvanced Optical Materials, EarlyView.
WSe2/InP hybrid platform is shown, enabling strain‐localized quantum emission. SEM confirms the hybrid structure, while PL spectra identify discrete emitters and second‐order correlation verifies single‐photon behavior. AFM profiling reveals nanoscale deformation, and the corresponding strain map highlights highly strained regions hosting the emitters,

Ionic Density‐Controlled Conjugated Polyelectrolytes for Interface Engineering in Inverted Colloidal PbS Quantum‐Dots Infrared Photodetector

open access: yesAdvanced Optical Materials, EarlyView.
This study demonstrates that conjugated polyelectrolytes with tunable ionic density can act as effective interfacial layers in inverted PbS quantum dot photodiodes. By enhancing dipole orientation and defect passivation at the ITO/QD interface, the devices exhibit suppressed dark current, improved photocurrent, and a record near‐infrared detectivity of
