Abstract

PURPOSE: To prevent the increase in injection carriers on the outside of stripe regions and obtain large optical output with a basic parallel lateral mode oscillation state by letting the active layer positioned on the outside of the stripe regions limiting current injection regions be a layer to absorb the injection carriers.
