Abstract
Damage resulting from irradiating oxide-confined vertical-cavity surfa ce-emitting lasers became significant (threshold shift approximate to 20%, peak power degradation approximate to 20%) at fluence levels appr oaching 1 x 10(13) protons/cm(2). The threshold current shifted to hig her values, and the peak light output power decreased. Forward-current annealing led to partial recovery of the performance of two of the th ree lasers for which annealing was attempted. Recent results[1-3] on p roton-implanted devices are summarized in a table.
