Patent attributes
A light emitting element according to the present disclosure includes: a GaN substrate; a first strain correction layer disposed above the GaN substrate and including InxGa1-xN of a first conductivity type where x is greater than 0 and less than or equal to 1; a first low refractive index layer disposed above the first strain correction layer, including In1-a-bGaaAlbN of the first conductivity type, and having relationships of (a/0.98)+(b/0.8)≥1, (a/1.02)+(b/0.85)≤1, and (a/1.03)+(b/0.68)≥1; a first clad layer disposed above the first low refractive index layer, including AlzGa1-zN of the first conductivity type where z is greater than or equal to 0.03 and less than or equal to 0.06, and having a refractive index higher than a refractive index of the first low refractive index layer; and an active layer disposed above the first clad layer.
