Abstract(in English) | High-power GaN-based laser diodes (LDs) are expected as light-source of various high-power applications. The catastrophic-optical-damage (COD) is a major failure mechanism to limit the output power, where optical absorption at a light-emitting facet causes an irreversible damage to the LDs. In this paper, a window structure in InGaN-based LDs to suppress the COD is demonstrated for the first time. The structure is formed by the MOCVD (metal organic chemical vapor deposition) growth over a recess placed besides of the ridge-waveguide. The In composition in the QW is reduced by controlling the local orientation angle at the sidewall of the recess. Thus formed window structure eliminates undesired optical absorption at the cleaved facet so that extremely high output power over 2W in narrow-stripe ridge-waveguide InGaN-based blue-violet LDs is achieved without any CODs. |
