SEMICONDUCTOR LIGHT EMITTING ELEMENT

摘要

A semiconductor light emitting element includes a semiconductor stack part that includes a light emitting layer, a diffractive face to which light emitted from the light emitting layer is incident, and convex portions or concave portions formed in a period which is longer than an optical wavelength of the light and is shorter than a coherent length of the light. The diffractive face reflects incident light in multimode according to Bragg's condition of diffraction and transmits the incident light in multimode according to the Bragg's condition of diffraction. The semiconductor stack part is formed on the diffractive face. The convex portions or the concave portions include a side surface and a curved portion which curves and extends to a center side of the convex portions or the concave portions from an upper end of the side surface.
