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.
