ResumoThe authors have developed 405 nm high-power laser diodes suitable for use in Blu-ray Disk systems, the next generation of large-capacity optical recording systems. Epitaxial lateral overgrowth was refined considering the spatial distribution of dislocation density in the lateral growth region to achieve satisfactory lifetimes. Improvements in the threshold/operating current, slope efficiency and characteristic temperature are discussed, in particular with respect to the effect of the location of an AlGaN electron-blocking layer.
