Measurement and modeling of microlenses fabricated on single-photon avalanche diode arrays for fill factor recovery

Edoardo Charbon, Juan Mata Pavia, Martin Wolf

Single-photon avalanche diode (SPAD) imagers typically have a relatively low fil factor, i.e. a low proportion of the pixel's surface is light sensitive, due to in-pixel circuitry. We present a microlens array fabricated on a 128x128 single-photon avalanch ...
