Burri, S. (author), Maruyama, Y. (author), Michalet, X. (author), Regazzoni, F. (author), Bruschini, C. (author), Charbon, E. (author)We present the architecture and three applications of the largest resolution image sensor based on single-photon avalanche diodes (SPADs) published to date. The sensor, fabricated in a high-voltage CMOS process, has a resolution of 512 × 128 pixels and a pitch of 24 ?m. The fill-factor of 5% can be increased to 30% with the use of microlenses....journal article 2014

Maruyama, Y. (author), Blacksberg, J. (author), Charbon, E. (author)A 1024 8 time-gated, single-photon avalanche diode line sensor is presented for time-resolved laser Raman spectroscopy and laser-induced breakdown spectroscopy. Two different chip geometries were implemented and characterized. A type-I sensor has a maximum photon detection efficiency of 0.3% and median dark count rate of 80 Hz at 3 V of excess...journal article 2013

A wide spectral range single-photon avalanche diode fabricated in an advanced 180 nm CMOS technologyMandai, S. (author), Fishburn, M.W. (author), Maruyama, Y. (author), Charbon, E. (author)We present a single-photon avalanche diode (SPAD) with a wide spectral range fabricated in an advanced 180 nm CMOS process. The realized SPAD achieves 20 % photon detection probability (PDP) for wavelengths ranging from 440 nm to 820 nm at an excess bias of 4V, with 30 % PDP at wavelengths from 520 nm to 720 nm. Dark count rates (DCR) are at...journal article 2012

Blacksberg, J. (author), Maruyama, Y. (author), Charbon, E. (author), Rossman, G.R. (author)We incorporate newly developed solid-state detector technology into time-resolved laser Raman spectroscopy, demonstrating the ability to distinguish spectra from Raman and fluorescence processes. As a proof of concept, we show fluorescence rejection on highly fluorescent mineral samples willemite and spodumene using a 128 × 128 single-photon...journal article 2011

Gersbach, M. (author), Trimananda, R. (author), Maruyama, Y. (author), Fishburn, M. (author), Cahrbon, E. et al (author)Imaging techniques based on time-correlated single photon counting (TCSPC), such as fluorescence lifetime imaging microscopy (FLIM), rely on fast single-photon detectors as well as timing electronics in the form of time-to-digital or time-to-analog converters. Conventional systems rely on stand-alone or small arrays (up to 32) of detectors and...conference paper 2010
