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 14):
A method of producing a surface light emitting semiconductor laser element according to  claim 11 , wherein in the step of forming the contact layer on the upper reflection layer, a plurality of contact layers are formed so that each Al composition decreases step-wise or gradually from the upper layer to the lower layer, and wherein in the step of forming the opening on the contact layer smaller than the opening of the insulation film to expose the upper reflector, the opening is formed on each contact layer so that each opening diameter decreases step-wise or gradually from the upper layer to the lower layer by utilizing a difference in etching rates by the fact that each Al composition decreases step-wise or gradually from the upper layer to the lower layer.
