Localization of single molecules with structured illumination and structured detection

open access: yesLight: Science & Applications
A new high-precision single-molecule localization scheme, ISM-FLUX, is an implementation of MINFLUX using image-scanning microscopy (ISM) with a single-photon avalanche diode (SPAD) array detector.

Artifact Removal in Long-Range Single Photon LiDAR via Waveforms-Guided Depth Image Estimation

open access: yesIEEE Photonics Journal
Single-photon light detection and ranging (LiDAR) has widespread applications due to the ultra-high sensitivity of the single-photon detector. However, the reconstruction has been plagued by multiple types of noise caused by crosstalk, dark counts, and ...

Vector‐Field Control and Emergent Basal‐Plane Anisotropy of Magnetic Textures in Noncentrosymmetric (Fe0.63Ni0.3Pd0.07)3P

open access: yesAdvanced Functional Materials, Volume 36, Issue 79, 1 October 2026.
A field‐driven transition from chiral stripes to an achiral fan state is observed in a tetragonal magnet and linked to a temperature‐dependent rotation of the effective Dzyaloshinskii–Moriya interaction axis. This interplay generates pronounced in‐plane anisotropy and provides a new route for controlling chiral spin textures in noncentrosymmetric ...

Optical control of single-photon negative-feedback avalanche diode detector

open access: yes, 2020
We experimentally demonstrate optical control of negative-feedback avalanche diode detectors using bright light. We deterministically generate fake single-photon detections with a better timing precision than normal operation. This could potentially open

High‐Speed Photoresponse of CVD‐Grown Lateral TMD Heterostructures

open access: yesAdvanced Functional Materials, Volume 36, Issue 79, 1 October 2026.
Internal electric fields generated by p‐n junctions and asymmetric Schottky barriers enhance the photoresponse speed in CVD‐grown monolayer TMD lateral heterostructures. This results in a 1.5‐2 orders of magnitude reduction in rise and fall times for optimized device configurations compared to homogeneous single‐material devices, enabling bandwidths ...

Behavioral Modeling of Photon Arrival Time for Time-of-Flight Measurement Circuit Simulation

open access: yesIEEE Photonics Journal, 2019
This letter proposes a behavioral model to estimate the statistical photon arrival time for time-of-flight (TOF) measurement circuit simulation. A theoretical model is derived to calculate the photon arrival rate by full consideration of a variety of ...

Timing properties of an avalanche diode for single photon counting

open access: yes, 2006
A new concept for a silicon single photon counter has been developed at the Semiconductor Laboratory of the Max-Planck-Institute for Physics. The concept combines the principles of a drift diode and an avalanche diode.

Toward Application of Nanodiamonds for In‐Situ Monitoring of Radicals in Liquid Phase Chemical Reactions

open access: yesphysica status solidi (a), Volume 223, Issue 18, 23 September 2026.
In many chemical reactions, short‐lived radical intermediates play a crucial role, while detecting them in situ remains challenging. The optically readable electronic spin of NV centers in diamond is a nanoscale sensor for such radical species. We demonstrate the successful in situ detection of the nitroxide radical 2,2,6,6‐TEMPO using NV center‐based ...
