| abstract | Disclosed surface emitting lasers are easy to manufacture, high yield and long service life. In the surface emitting laser, the target oxide layer is included as part of the low refractive index layer of the upper semiconductor distribution Bragg reflector, and the low refractive index layer including the target oxide layer includes two intermediate layers adjacent to the target oxide layer, and the intermediate layer. It includes two low refractive index layers adjacent to. The Al content of the intermediate layer is lower than the Al content of the oxide layer to be selected, and the Al content of the low refractive index layer is lower than the Al content of the oxide layer to be selected. By such a configuration, more control over the thickness and oxidation rate of the oxide layer is possible, thereby reducing the thickness variation of the oxide layer. |
