Additional Crosstalk Suppression in Avalanche Photodiodes

There is provided a photodiode array. The photodiode array includes a substrate that has an optical interface surface arranged for accepting external input radiation into the substrate. A plurality of photodiodes are disposed at a substrate surface opposite the optical interface surface of the substrate. Each photodiode in the plurality of photodiodes includes a photodiode material that generates light into the substrate as a result of external input radiation absorption by the photodiode. There is aperiodic photodiode placement along at least one direction of the array.
