SURFACE EMITTING LASER DEVICE, SURFACE EMITTING LASER ARRAY, OPTICAL SCANNING DEVICE, IMAGE FORMING APPARATUS, AND METHOD OF MANUFACTURING THE SURFACE EMITTING LASER DEVICE
摘要:
A surface emitting laser device includes a substrate and plural semiconductor layers laminated on the substrate, the plural semiconductor layers including a first semiconductor multi-layer film including aluminum (Al), an active layer, and a second semiconductor multi-layer film, a light emitting section having a mesa structure being formed on the first semiconductor multi-layer film. When viewed in a direction orthogonal to a surface of the substrate, an outer shape of the first semiconductor multi-layer film is a macroscopically smooth shape without an angular corner, and a side surface of the first semiconductor multi-layer film is coated with a passivation film and a protection film.
