Abstract
The invention relates to an avalanche photodetector having a charge-multiplication region which is spatially separated from the detector surfaces. This photodetector includes an absorptive region, a first region overlying the absorptive region and having a central zone which is thicker than a surrounding peripheral zone and a second region overlying the first region. The avalanche region is then restricted to the thicker central zone of the first region.
