Claim:
1. A semiconductor light emitting apparatus comprising: a semiconductor light emitting device having a layered semiconductor layer configured by layering at least two semiconductor layers, and a light emitting layer to emit first light; and a wavelength conversion member that covers at least a part of the semiconductor light emitting device, absorbs at least a part of the first light and that emits second light with a wavelength different from that of the first light, wherein the semiconductor light emitting device is provided with a fine structure layer, as a component, including dots comprised of a plurality of convex portions or concave portions extending in an out-of-plane direction on one of main surfaces forming the semiconductor light emitting device, wherein the fine structure layer forms a two-dimensional photonic crystal controlled by a pitch between the dots that is an inconstant pitch that increases and decreases periodically, and wherein the two-dimensional photonic crystal includes at least two periods that each have a long period unit, of the inconstant pitch that increases and decreases periodically, of 1.3 μm or more.
