    摘要: A surface emitting laser element includes a mesa structure of a semiconductor multilayer film formed to have a convex cross section. A first insulating film of an inorganic material is formed on a side surface of the mesa structure, and on the first insulating film, a resin layer is formed to fill a space surrounding the mesa structure. A second insulating film of an inorganic material is formed on the resin layer, and an upper contact electrode with an electrode opening exposing part of the top surface of the mesa structure is formed on the second insulating film and the mesa structure. With this construction, oxidation and alteration of the resin layer during fabrication of the element can be suppressed to bury the mesa structure with no gap created. Therefore, a semiconductor light-emitting element with high reliability can be provided.

    摘要: According to the present invention, a first p-side electrode 7A made of metal which is provided with regularly arranged holes 10 having a diameter smaller than a laser oscillation wavelength and a second p-side electrode 7B arranged around the periphery of the first p-type electrode 7A are used as a p-side mirror of a surface-emitting laser. Light in a resonator formed of a p-side electrode 7 and an n-type mirror 2 is first converted to a surface plasmon and then reconverted to the light by the p-side electrode 7A, and then emitted outside the resonator. This improves the light transmittance, thereby permitting use of metal which is considered to have inherently low light transmittance as a material for the p-side electrode 7. If the p-side electrode 7 is made of metal, operating voltage is reduced and heat dissipation improves, without causing a spike in a valence band, which occurs when a semiconductor layer is used. Further, due to the nonlinear effect of the mirror, optical feedback to the inside of the resonator is controlled, whereby a laser device with excellent noise characteristic is obtained.
