Abstract:
1. A nitride semiconductor light-emitting device having an optical waveguide, the nitride semiconductor light-emitting device comprising, in the following order, at least: a first cladding layer; an active layer; and a second cladding layer, wherein the second cladding layer includes (i) a transparent conductive layer comprising a transparent conductor and (ii) a nitride semiconductor layer comprising a nitride semiconductor, the nitride semiconductor layer being formed closer to the active layer than the transparent conductive layer; wherein the nitride semiconductor comprises AlxInyGa1-x-yN, where 0<x≦0.82, 0<y≦0.18, and 0≦1-x-y<1; wherein a material of the transparent conductor is one of tin-added indium oxide, antimony-added tin oxide, and zinc oxide; wherein the transparent conductive layer has a film thickness greater than 100 nm.
