Abstract:
A surface light emitting semiconductor laser element, comprises a substrate, a lower reflector including a semiconductor multi-layer disposed on the substrate, an active layer disposed on the lower reflector, an upper reflector including a semiconductor multi-layer disposed on the active layer, a compound semiconductor layer having a first opening for exposing the upper reflector and extending over the upper reflector, and a metal film having a second opening for exposing the upper reflector disposed inside of the first opening and extending over the compound semiconductor layer, wherein the metal film and the compound semiconductor layer constitute a complex refractive index distribution structure where a complex refractive index is changed from the center of the second opening towards the outside. A method of emitting laser light in a single-peak transverse mode is also provided.

Claim (Index 11):
A method of producing a surface light emitting semiconductor laser element, comprising the steps of:\n sequentially laminating a lower reflector including a semiconductor multi-layer, an active layer, an upper reflector including a semiconductor multi-layer having a layer with a high Al content, and a contact layer on a substrate, etching the upper reflector having the layer with the high Al content to form a mesa post, forming an insulation film on the contact layer of the mesa post and a side of the mesa post, forming an opening on the insulation film over the contact layer to expose the contact layer, forming an opening on the contact layer smaller than the opening of the insulation film to expose the upper reflector, forming a metal film for constituting an electrode on the upper reflector and the contact layer, and forming an opening on the metal film smaller than the opening on the contact film to expose the upper reflector.
