Abstract
An n-GaAs current blocking layer is formed on a p-AlGaInP first cladding layer, on sides of a ridge portion and in a region on the upper surface of the ridge portion above a window region. Raised portions are formed in a p-GaAs cap layer in regions in the vicinity of facets, while raised regions are formed in the regions of a first electrode in the vicinity of the facets. A second electrode having a thickness larger than the height of the raised regions is formed on the region between the raised regions of the first electrode.
