Abstract
A photodetection device including a diode array and a method for production thereof. In the device, each diode of the array includes an absorption region having a first bandgap energy and a collection region having a first doping type, and adjacent diodes in a network are separated by a trench including sides and a bottom. The bottom and sides of the trench form a stabilization layer having a second doping type, opposite the first doping type, and a bandgap energy greater than the first bandgap energy of the absorption regions.
