| 英文摘要 | A surface emitting laser element is disclosed. The surface emitting laser element includes a resonator structural body including an active layer, first and second semiconductor distributed Bragg reflectors which sandwich the resonator structural body, and a confinement structure which can confine an injection current and a lateral mode of oscillation light at the same time by being formed with selective oxidation of a layer to be selectively oxidized containing aluminum in the first semiconductor distributed Bragg reflector. A thickness of the layer to be selectively oxidized is 28 nm, and a temperature when an oscillation threshold current becomes a minimum value is approximately 17° C. |
