Developing large arrays of single-photon avalanche diodes (SPADs) with on-chip time-correlated single-photon counting (TCSPC) capabilities continues to be a difficult task due to stringent silicon real estate constraints, high data rates and system complex ...

We realized subsurface fluorescence LiDAR with a large format single-photon avalanche diode array capable of localizing and quantifying concentration of fluorescent molecules in heavily scattering media, such as tissue, with submillimeter depth accuracy. ( ...

Scintillators play a key role in the detection chain of several applications which rely on the use of ionizing radiation, and it is often mandatory to extract and detect the generated scintillation light as efficiently as possible. Typical inorganic scinti ...

Integrated receiving circuit for radiofrequency signals comprising: an amplifying element (2) using the multiplication zone (5) of a reverse biased semiconductor junction (3, 4) operating in Geiger mode for amplifying an input radiofrequency signal (Vin) a ...

CMOS Single-Photon Avalanche Diodes (SPADs) have broken into the mainstream by enabling the adoption of imaging, timing, and security technologies in a variety of applications within the consumer, medical and industrial domains. The continued scaling of te ...

Compressive Raman imaging has emerged as a promising technique to speed up chemical imaging by compressing the data during acquisition. Yet, current scanning imaging speed is fundamentally limited by the sensors pixel dwell times of at best 1µs. Here, we i ...

The goal of this paper is to introduce CMOS-based single-photon detectors in terms of technology and applications. We cover background and recent progress on the detectors and describe emerging applications based on the technology. ...

Over the past decade, significant progress in quantum technologies has been made, and hence, engineering of these systems has become an important research area. Many researchers have become interested in studying ways in which classical integrated circuits ...

In this paper a method is presented for automatically generating a parameterized model of integrated inductors accounting for geometry and substrate effects. A multiparameter Krylov-subspace based moment matching method is used to reduce the three-dimensio ...

Recently, we demonstrated the potential of single-photon i magers in diffuse optical tomography (DOT). We present the advances of a new algorithm based on optical setups using this kind of sensors. ...

True random number generators (TRNGs) allow the generation of true random bit sequences, guaranteeing the unpredictability and perfect balancing of the generated values. TRNGs can be realised from the sampling of quantum phenomena, for instance, the detect ...

Quantum computing holds the promise to achieve unprecedented computation power and to solve problems today intractable. State-of-the-art quantum processors consist of arrays of quantum bits (qubits) operating at a very low base temperature, typically a few ...

We describe a novel type of two-photon interferometer, capable of spectral binning, for quantum-assisted astrometry. We also demonstrated a single-photon spectrometer with spectral and timing resolutions of 0.1 nm and 50 ps, which can be used for this purp ...

In many clinical applications it is relevant to observe dynamic changes in oxygenation. Therefore the ability of dynamic imaging with time domain (TD) near-infrared optical tomography (NIROT) will be important. But fast imaging is a challenge. The data acq ...

The transistor compact model is crucial but has yet to mature for cryogenic electronics. This paper presents a sophisticated analytical model of the MOSFET subthreshold current at cryogenic temperatures, accounting for the thermionic, hopping, source-to-dr ...

In near infrared fluorescence-guided surgical oncology, it is challenging to distinguish healthy from cancerous tissue. One promising research avenue consists in the analysis of the exogenous fluorophores' lifetime, which are however in the (sub-)nanosecon ...

Single-photon avalanche diodes (SPADs) are detectors capable of capturing single photons and of performing photon counting. SPADs have an exceptional temporal resolution and are thus highly suitable for time-resolved imaging applications. Applications span ...

We introduce a new family of single-photon avalanche diodes (SPADs) with enhanced depletion regions in a 55-nm Bipolar-CMOS-DMOS (BCD) technology. We demonstrate how to systematically engineer doping profiles in the main junction and in deep p-well layers ...
