A light emitting device includes a semiconductor layer having a light extraction surface and side surfaces. The semiconductor layer includes a cladding layer and an active layer. The cladding layer has the extraction surface and a cladding layer side surface of the side surfaces, the cladding layer side surface being arranged at a first angle to the extraction surface. The active layer has an active layer side surface of the side surfaces, the active layer side surface being arranged at a second angle different from the first angle to the extraction surface.
