We review the advancement of the research toward the design and implementation of quantum plenoptic cameras, radically novel 3D imaging devices that exploit both momentum–position entanglement and photon–number correlations to provide the typical refocusin ...

Multiply excited states in semiconductor quantum dots feature intriguing physics and play a crucial role in nanocrystal-based technologies. While photoluminescence provides a natural probe to investigate these states, room-temperature single-particle spect ...

Objective: Time-domain diffuse optical imaging (DOI) requires accurate forward models for photon propagation in scattering media. However, existing simulators lack comprehensive experimental validation, especially for non-contact configurations with oblique illumination. This study rigorously evaluates three widely used open-source simulators, including MMC (Mesh-based Monte Carlo), NIRFASTer, and Toast++ (the latter two are finite-element method (FEM)-based), using time-resolved experimental data. Approach

Quantum dots (QDs) offer a tunable and technology-compatible platform for quantum light-matter interactions and the inspiring technology that comes along with it. The extent of this promise is directly related to our ability to understand and control this interaction. However, understanding the electronic dynamics is tremendously challenging, in large part due to the large range of time scales in which they occur. Spectral diffusion (SD), the stochastic fluctuation in the energy of photons emitted from a Q

This paper presents our work on a 65k pixel single-photon avalanche diode (SPAD) based imaging sensor realized in a 0.35 mu m standard CMOS process. At a resolution of 512 by 128 pixels the sensor is read out in 6.4ps to deliver over 150k monochrome frames ...

The analysis of proteins in the gas phase benefits from detectors that exhibit high efficiency and precise spatial resolution. Although modern secondary electron multipliers already address numerous analytical requirements, additional methods are desired f ...

Significance Fluorescence-guided surgery (FGS) utilizes molecular contrast agents to highlight critical structures or pathological tissues in real time. The premise of FGS is to enable precise surgical decision-making through accurate visualization and quantitative assessment of fluorophore distribution. However, strong effects of diffusion and absorption of fluorescent light in tissue confound fluorescence images, preventing accurate quantitative assessment of the concentration and distribution of fluoresc

In this paper, we report on SwissSPAD2, an image sensor with 512 x 512 photon-counting pixels, each comprising a single-photon avalanche diode (SPAD), a 1-b memory, and a gating mechanism capable of turning the SPAD ON and OFF, with a skew of 250 and 344 p ...

In this article, we report on SwissSPAD3 (SS3), a 500 x 500 pixel single-photon avalanche diode (SPAD) array, fabricated in 0.18-mu m CMOS technology. In this sensor, we introduce a novel dual-gate architecture with two contiguous temporal windows, or gate ...

The idea of exploiting quantum features of light to perform more precise astrophysical measurements is a long-desired goal of both the optics and astrophysics communities, but only recently have theoretical proposals started to be experimentally implemente ...

SPADnet is a sensor platform for the detection and processing of gamma photons generated in a PET system. SPADnet uses the novel technique of deferred coincidence detection, whereas timestamps associated with gamma events and their energy are routed at hig ...

The performance of SwissSPAD2 (SS2), a large scale, widefield time-gated CMOS SPAD imager developed for fluorescence lifetime imaging, has recently been described in the context of visible range and fluorescence lifetime imaging microscopy (FLIM) of dyes w ...

Megapixel single-photon avalanche diode (SPAD) arrays have been developed recently, opening up the possibility of deploying SPADs as general-purpose passive cameras for photography and computer vision. However, most previous work on SPADs has been limited ...

In the planned LHCb RICH (Ring Imaging Cherenkov Detector) upgrade II, silicon photomultipliers (SiPMs) are considered as one of the most promising photodetector candidates. They can meet all of the performance requirements of upgraded RICH detector, except for the neutron irradiation hardness. During the whole experiment run time, the photodetectors are expected to receive accumulated dose of about 1013 1-MeV neutron equivalent /cm2. For the SiPMs to keep sufficient performance after such a dose, a combina

Understanding exciton-exciton interaction in multiply excited nanocrystals is crucial to their utilization as functional materials. Yet, for lead halide perovskite nanocryst-als, which are promising candidates for nanocrystal-based technologies, numerous c ...

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 ...

Single-photon avalanche diode (SPAD) arrays are solid-state detectors that offer imaging capabilities at the level of individual photons, with unparalleled photon counting and time-resolved performance. This fascinating technology has progressed at a very ...

A significant number of cryogenic low -noise amplifiers (cryo-LNAs) are required for the readout of superconducting nanowire detector (SNWD) arrays. It is desirable to have compact cryo-LNAs in place so that the size of the readout circuitry for the SNWD a ...

We present the world's first backside-illuminated (BSI) single-photon avalanche diode (SPAD) based on standard silicon-on-insulator (SOI) complementary metal-oxide semiconductor (CMOS) technology. This SPAD achieves a good dark count rate (DCR) after backs ...

Spontaneous Raman microscopy is well-known for its remarkable chemical contrast yet suffers from slow acquisition speeds. Recently, the compressive Raman microspectroscopy framework has shown that a significant speed advantage is brought by leveraging shot ...
