Abstract
200 MeV proton damage effects on multi-quantum well GaAs/GaAlAs laser diodes are studied. The threshold current damage factor can vary from 1.73 to 4.60x10(-15) cm(2)/p for different bias conditions and from 1. 52 to 3.58x10(-15) cm(2)/p for different incident directions. A simple model, based on threshold current damage factor, is presented to quan tify the degradation of optical power. Preliminary annealing effects a re also presented. The annealing effects are greater for devices short ed during irradiation than for those biased at I-bias=35mA.
