Paper Abstract

Commercial InGaAsP laser diodes were tested for radiation-induced changes in their characteristics when irradiated by gamma and proton radiation at several temperatures. The spectral output, threshold current and frequency response of the laser diodes were measured as a function of dose while maintaining the devices at the three temperatures, 71°C, near ambient and -30°C during the exposures. The laser diodes showed small changes to the threshold current under radiation but in general were resistant to the radiations. The details of the experiments and the temperature dependence observed are presented and the comparative effects of gamma and proton radiation are discussed.
