Multifrequency-resolved Hanbury Brown–Twiss effect

Edoardo Charbon, Claudio Bruschini, Tommaso Milanese, Samuel Burri

The Hanbury Brown–Twiss (HBT) effect holds a pivotal place in intensity interferometry and gave a seminal contribution to the development of quantum optics. To observe such an effect, both good spectral and timing resolutions are necessary. Most often, the ...

Teaching single-photon detection metrology with off-the-shelf CMOS SPAD detectors

Edoardo Charbon, Claudio Bruschini, Ekin Kizilkan, Utku Karaca

The fabrication of the first CMOS single-photon avalanche diodes (SPADs) back in 2003 paved the way to a range of photodetection applications based on single-photon detection, photon counting, and photon time-stamping. In turn, it has become more and more ...

Predicting Important Photons for Energy-Efficient Single-Photon Videography

Edoardo Charbon, Claudio Bruschini

Single-photon avalanche diodes (SPAD) detect individual photons with fine temporal resolutions, enabling capabilities like imaging in near-total darkness, extreme dynamic range, and rapid motion. Due to these capabilities, and coupled with the recent emerg ...

Mismatch and Retention Time Analysis of Drams Down to 4 K

Claudio Bruschini

This paper explores the retention time (RT) properties of dynamic random-access memory (DRAM) arrays at cryogenic temperatures (4 K). We provide an in-depth examination of leakage sources to elucidate RT behaviour across different temperatures, and we cond ...

Beneath the surface: revealing deep-tissue blood flow in human subjects with massively parallelized diffuse correlation spectroscopy

Edoardo Charbon, Claudio Bruschini, Arin Can Ülkü, Michael Alan Wayne

Significance: Diffuse correlation spectroscopy (DCS) allows label-free, non-invasive investigation of microvascular dynamics deep within tissue, such as cerebral blood flow (CBF). However, the signal-to-noise ratio (SNR) in DCS limits its effective cerebra ...

Wide-field fluorescence lifetime imaging of single molecules with a gated single-photon camera

Edoardo Charbon, Claudio Bruschini, Aleksandra Radenovic, Matteo Dal Peraro, Nathan Cyprien Arsène Ronceray

Fluorescence lifetime imaging microscopy (FLIM) is a powerful tool to discriminate fluorescent molecules or probe their nanoscale environment. Traditionally, FLIM uses time-correlated single-photon counting (TCSPC), which is precise but intrinsically low-t ...

Mesoscopic light-sheet imaging set-up for 3D SWIR fluorescence intensity and NIR fluorescence lifetime imaging

Edoardo Charbon, Claudio Bruschini

Fluorescence lifetime imaging offers the unique ability to monitor the molecular status of the tissue microenvironment. However, the scattering nature of tissues remains a challenge for mesoscopic 3D high resolution imaging. We introduce the design of a me ...

Massively multiplexed wide-field photon correlation sensing

Edoardo Charbon, Claudio Bruschini, Michael Alan Wayne

Temporal photon correlations have been a crucial resource for quantum and quantum-enabled optical science for over half a century. However, attaining non-classical information through these correlations has typically been limited to a single point (or, at ...
