Abstract
The effects of gamma radiation on Fabry–Perot interband cascade lasers (ICLs) were investigated. Two ICLs were exposed to cobalt-60 gamma rays for a total dose of 500 krad(Si) each. The ICLs do not show any evidence of changes in performance, including output power, threshold current, slope efficiency, or spectral frequency. These results demonstrate that ICLs are insensitive to gamma irradiation up to exposure rates above those normally encountered within a shielded spacecraft.
