Abstract :
Damage resulting from irradiating oxide-confined vertical-cavity surface-emitting lasers became significant (threshold shift ≈20%, peak power degradation ≈20%) at fluence levels approaching 1×10 13 protons/cm2. The threshold current shifted to higher values, and the peak light output power decreased. Forward-current annealing led to partial recovery of the performance of two of the three lasers for which annealing was attempted. Recent results on proton-implanted devices are summarized in a table
