We studied long-wavelength vertical-cavity surface-emitting laser diodes (LW-VCSELs) emitting in the 1.4-1.7 µm range under gamma radiation up to 9 MGy and 36 MeV protons up to 1013 p/cm², in order to compare the impact of both ionizing and displacement damage on their optical and electrical properties. The limited threshold shift and slope efficiency degradation of these state-of-the-art electrically-pumped laser diodes allow us to envisage data and sensor applications in various radiation environments.
