Abstract:
1. A semiconductor light emitting device comprising: a stacked body including a first semiconductor layer of a first conductivity type, a second semiconductor layer of a second conductivity type, and a light emitting layer provided between the first semiconductor layer and the second semiconductor layer, the stacked body having a stacking direction from the first semiconductor layer to the second semiconductor layer, a first direction perpendicular to the stacking direction, and a second direction perpendicular to the first direction and the stacking direction, the stacked body having a first end surface and a second end surface opposed to the first end surface in the first direction; a first electrode provided in contact with the first semiconductor layer, the first semiconductor layer being disposed between the first electrode and the light emitting layer; and a second electrode provided in contact with the second semiconductor layer, the second semiconductor layer being disposed between the second electrode and the light emitting layer, light emitted from the light emitting layer being resonated between the first end surface and the second end surface, the second semiconductor layer including: the second semiconductor layer including, the second electrode including a narrow part and a wide part, the narrow part being in contact with the fourth portion, the wide part being in contact with the second portion, a width of the narrow part along the second direction being narrower than a width of the wide part along the second direction and narrower than the width of the fourth portion along the second direction.
