Abstract: A semiconductor light emitting device includes: a nitride semiconductor light emitting element including a nitride semiconductor substrate having a polar or semipolar surface and a nitride semiconductor multilayer film stacked on the polar or semipolar surface; and a mounting section to which the element is mounted. The nitride semiconductor multilayer film includes an electron block layer. The electron block layer has a smaller lattice constant than the nitride semiconductor substrate. The mounting section includes at least a first mounting section base. The first mounting section base is located close to the nitride semiconductor light emitting element. The first mounting section base has a lower thermal expansion coefficient than the nitride semiconductor multilayer film. The first mounting section base has a lower thermal conductivity than the nitride semiconductor multilayer film.

Abstract: Provided is a highly reliable nitride semiconductor laser element having a robust end face protection film not being peeled even in laser operation. The nitride semiconductor laser element includes: a semiconductor multi-layer structure including a group III nitride semiconductor and having a light-emitting end face; and a protection film including a dielectric multi-layer film and covering the light-emitting end face of the semiconductor multi-layer structure. The protection film includes an end face protection layer and an oxygen diffusion suppression layer arranged sequentially in stated order from the light-emitting end face. The end face protection layer includes a crystalline film comprising nitride including aluminum. The oxygen diffusion suppression layer has a structure in which a metal oxide film is between silicon oxide films. The metal oxide film is crystallized by laser light.
