Benchmarking Organic Photodiodes at the Noise Floor

Advanced Optical Materials, EarlyView.
A precise measurement framework based on a calibrated, ultra‐low‐noise automated setup with open‐source Python scripts enables accurate benchmarking of photodiodes. The unique combination of time‐dependent current measurement under dark conditions, followed by continuous‐wave faint illumination, facilitates reliable extraction of photocurrent near ...

Zone‐Sectored Organic Crystals with Spatially Resolved Exciton Dynamics

Advanced Optical Materials, EarlyView.
Novel type of rubrene microcrystals in the orthorhombic phase are grown exhibiting spatial contrast in spectra and dynamics due to differences in unit cell orientation. Distinct zones selectively host redshifted luminescence band at ≈650 nm driven by high photon absorption.

Diameter Dependence of Light Absorption in GaAs Nanowires Evidenced by Photoluminescence Spectroscopy

Advanced Optical Materials, EarlyView.
Photoluminescence spectroscopy is introduced as a qualitative method to probe light absorption in highly phase‐pure GaAs nanowire arrays and single nanowires, for which direct absorption measurements are challenging. Using defect‐line saturation and the exciton‐to‐plasma transition as indicators for the density of photogenerated charge carriers, a ...

Probing Ultrafast Coherent Bandgap Modulation in Monolayer WSe2 by Nonlinear Optics

Advanced Optical Materials, EarlyView.
This work sheds light on how resonant nonlinear optics blursthe line between perturbative and non‐perturbative nonlinear optics. Measured deviationsfrom the quadratic second‐harmonic scaling near the excitonic resonance arisefrom optical Stark and Bloch‐Siegert shifts. The experimental results arefurther underpinned by analytical and numerical analysis
