One of the most downloaded articles of Light: Science & Applications

Claudio Bruschini and Edoardo Charbon's latest research has been selected as one of its twenty most downloaded articles for the year 2020 by the Nature Publishing Group's affiliated journal Light: Science & Applications.

The Advanced Quantum Architecture laboratory has been pioneering Single-Photon Avalanche Diodes (SPADs) since 2003, in particular compact devices and arrays implemented in standard CMOS electronics technologies. Substantial improvements have been made on this miniature photodetector, which acts like a 3-in-1 light particle detector, counter and stopwatch with picosecond precision. The same applies to the sensor architectures which have been explored over the years, and to the broad application spectrum of SPAD-based imagers.

Claudio Bruschini, Harald Homulle, Edoardo Charbon and colleagues have therefore decided to review these fascinating developments from the angle of biophotonics applications such as Fluorescence Lifetime Imaging (FLIM), super-resolution microscopy, time-resolved Raman spectroscopy, near-infrared optical tomography and Positron Emission Tomography (PET), to name a few.
