Dark current suppression via depletion region engineering is performed to eliminate Shockley-Read-Hall, Radiative and Trap-Assisted-Tunnelling dark currents in various atmospheric transmission windows. Effectiveness of the suppression technique is compared for all types of detectors revealing the dominant mechanisms and the performance limitations.
