(author), Wang, Tzu Jui (author), Huang, Kuo Chin (author), Yamashita, Yuichiro (author), Yaung, Dun Nian (author), Charbon-Iwasaki-Charbon, E. (author)We present a high-performance back-illuminated three-dimensional stacked single-photon avalanche diode (SPAD), which is implemented in 45-nm CMOS technology for the first time. The SPAD is based on a P<sup>+</sup>/Deep N-well junction with a circular shape, for which N-well is intentionally excluded to achieve a wide depletion region, thus...journal article 2018

(author), Boller, K.J. (author)We report on a novel type of laser in which a semiconductor optical amplifier (SOA) receives frequency-selective feedback from a glass-waveguide circuit. The laser we present here is based on InP for operation in the 1.55 µm wavelength range. The Si3N4/SiO2 glass waveguide circuit comprises two sequential high-Q ring resonators. Adiabatic...conference paper 2014
