Abstract
The effect of current annealing for GaInNAs laser characteristics was investigated and compared with that of thermal annealing. It was found that the threshold current density was largely reduced by the current annealing and became comparable level as thermal annealing. The wavelength shift after current annealing was small contrary to the thermal annealing showing large blue shift. From the experimental result, we indicated that the annealing effects of the threshold current reduction and wavelength shift depends on different mechanisms.
