    摘要： Provided is a buried ridge waveguide laser diode that has improved temperature characteristics and can reduce optical loss by a leakage current. The buried ridge waveguide laser diode includes: a ridge region that extends vertically with a constant width and is composed of a selective etching layer and a first compound layer formed of a first conductive type material on a portion of the clad layer; and a p-n-p current blocking layer that has a thickness identical to the depth of the ridge region on the clad layer outside the ridge region and includes a second compound layer formed of a second conductive type material opposite to the first conductive type material. At this time, the current blocking layer includes the first compound layer extending on the second compound layer.

    摘要： Provided is an external cavity laser light source. The light source includes a substrate, an optical waveguide, and a current blocking layer. The optical waveguide includes a passive waveguide layer, a lower clad layer, an active layer, and an upper clad layer that are sequentially stacked on the substrate and is divided into regions including a linear active waveguide region, a bent active waveguide region, a tapered waveguide region, and a window region. The current blocking layer was formed an outside of the active layer to reduce leakage current. The linear and bent active waveguide regions have a buried heterostructure (BH), and the tapered waveguide region and the window region have a buried ridge stripe (BRS) structure. The passive waveguide layer a width substantially equal to a maximal width of the tapered waveguide region at least in the bent active waveguide region, the tapered waveguide region, and the window region.
