    摘要: Provided is a resonator of a hybrid laser diode. The resonator includes: a substrate including a semiconductor layer where a hybrid waveguide, a multi-mode waveguide, and a single mode waveguide are connected in series; a compound semiconductor waveguide, provided on the hybrid waveguide of the semiconductor layer, having a tapered coupling structure at one end of the compound semiconductor waveguide, the tapered coupling structure overlapping the multi-mode waveguide partially; and a reflection part provided on one end of the single mode waveguide. The multi-mode waveguide has a narrower width than the hybrid waveguide and the single mode waveguide has a narrower width than the multi-mode waveguide.

    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.
