Abstract
The invention concerns a photodiode array, and the method for producing same, comprising—a cathode comprising at least one substrate layer () made from a material from the indium phosphide family and one active layer () made from a material from the gallium indium arsenide family, and characterized in that the array further comprises at least two sorts of doped regions of the same type at least partially formed in the active layer ():—first doped regions () forming, with the cathode, photodiodes for forming images,—at least one second doped region () absorbing excess charge carriers so as to discharge them.
