Abstract
A light receiver () having a plurality of avalanche photodiode elements () each configured to be biased with a bias voltage above a breakdown voltage and thus to be operated in a Geiger mode for triggering a Geiger current upon light reception, the light receiver () comprising a plurality of bias voltage terminals (-) providing different bias voltages, wherein the avalanche photodiode elements () form a plurality of groups (-), and wherein the avalanche photodiode elements () of a group (-) are each supplied with a same one of the different bias voltages.
