Abstract: PURPOSE: An asymmetric waveguide laser diode is provided to lower threshold current density and increase a slope effect by reducing optical loss of a long wavelength laser diode. CONSTITUTION: An asymmetric waveguide laser diode includes an active layer, an n-cladding layer, a p-cladding layer, and a substrate. The active layer includes a first side and a second side. The n-cladding layer is formed on the first side of the active layer. The p-cladding layer is formed on the second side of the active layer. The substrate is used for supporting a stacked structure including the active layer and the cladding layers. A refractive index of the p-cladding layer is lower than a refractive index of the n-cladding layer.
