Approche méthodologique de l'impact de l'environnement radiatif spatial sur les propriétés intrinsèques d'une diode laser

Abstract : The radiation matter interaction is well known and documented. However, studies concerning the impact of a radiative environment on laser diodes are rare, and usually consider the device as a black box, and only their extrinsic properties are studied. We propose to study laser diodes using a novel methodology, based on the analysis of both the optical, the electrical, and the dynamic properties of the laser diode. We show that this methodology enables to deduce the intrinsic parameters of the studied devices. This methodology is afterwards applied to the study of the space environment impact on laser diodes emitting at 852 nm, which could be potentially used for atom cooling in embedded caesium atomic clocks. Such systems could be embedded within Pharao and Galileo spatial programs. Therefore assessing their hardness to the radiative space environment is crucial. To further generalise this methodology, we apply it to advanced laser diodes based on tensile strained GaInNAs/InP and on InAs quantum dash laser diodes, both emitting at 1.55 µm.
