Single-Photon Computational Imaging System Based on Multi-Pixel Photon Counter

Photonics
Existing single-photon computational imaging systems always combine single-photon avalanche diode (SPAD)/photomultiplier tube (PMT) and time-correlated single-photon counting (TCSPC) together to collect the signals for imaging.

Integration of hBN Single‐Photon Emitters Into a Hybrid Optomechanical Membrane‐In‐The‐Middle Fiber‐Cavity

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
Deterministic manipulation of hexagonal boron nitride (hBN) flakes enables single‐photon emitters (SPEs) to be integrated into a fiber‐based Fabry–Pérot membrane‐in‐the‐middle cavity. Cavity coupling enhances and spectrally funnels the broadband emitter fluorescence, while allowing access to mechanical membrane modes for future hybrid optomechanical ...

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

IEEE 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

Advanced 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 ...

High‐Speed Photoresponse of CVD‐Grown Lateral TMD Heterostructures

Advanced 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

IEEE 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 ...

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

physica 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 ...
