40-nm SPAD-Array Detection System for Ultra-Fast Raman Spectroscopy
Biomedical opticsRaman Spectroscopy for protein sequencing requires fast detection systems able to manage fluorescence rejection. We propose a 40-nm SPAD-Array system-on-chip with an integrated gate generation block to time-filter fluorescence photons.

High performance compound semiconductor SPAD arrays
SPIE Proceedings, 2016Aggregated compound semiconductor single photon avalanche diode (SPAD) arrays are emerging as a viable alternative to the silicon photomultiplier (SiPM). Compound semiconductors have the potential to surpass SiPM performance, potentially achieving orders of magnitude lower dark count rates and improved radiation hardness.

Characterization of SPAD Arrays: First Results
2006SPAD detectors are very promising for astrophysical applications. Large arrays are crucial to cover as much of the focal plane as possible. STMicroelectronics has developed various monolithic arrays of SPAD. At present, the manufacturing of 5×5 arrays (each with an active area of 40 μm and pitch between adjacent pixels of 240 μm) is completed and ...

32 channels SPAD array for single photon timing applications
2012 IEEE Nuclear Science Symposium and Medical Imaging Conference Record (NSS/MIC), 2012Many applications require photodetectors with single-photon sensitivity and high timing resolution. We present a module based on a linear array of 32 Single-Photon Avalanche Diodes (SPADs) for multi-channel Time-Correlated Single-Photon Counting (TCSPC) applications.

The new generation of SPAD--Single-Photon Avalanche Diodes arrays
Il Nuovo Cimento C, 2007In the last years the single-photon detection with silicon devices has become an important goal. Here we present the performance of a new generation of single-photon avalanche diodes manufactured by ST-Microelectronics. The 5 x 5 array configuration has been also realized and the performances, in terms of crosstalk and common readout mode, have been ...
