Title:
PHOTODETECTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/146725
Kind Code:
A1
Abstract:
This photodetector device is equipped with an avalanche photodiode array substrate 10 comprising a compound semiconductor. In the avalanche photodiode array substrate 10, a plurality of avalanche photodiodes 20 that operate in Geiger mode are arranged two-dimensionally. A circuit board 50 is provided with a plurality of output units 30 that are connected together in parallel and form at least one channel 40. The output units 30 are each provided with a passive quenching element 31 and a capacitative element 32. The passive quenching element 31 is connected in series to at least one of the plurality of avalanche photodiodes 20. The capacitative element 32 is connected in series to at least one avalanche photodiode 20 and is connected in parallel to the passive quenching element 31.
