Abstract This surface-emitting laser device comprises: a first reflective layer; an active region disposed over the first reflective layer; an aperture region which is disposed over the active region and comprises an aperture and an insulating region; a second reflective layer disposed over the aperture region; and a second electrode electrically connected to the second reflective layer. The second electrode comprises first to sixth conductive layers. The first conductive layer may comprise Ti, and the sixth conductive layer may comprise Au. L'invention concerne un dispositif laser à émission de surface comprenant : une première couche réfléchissante ; une région active disposée sur la première couche réfléchissante ; une région d'ouverture qui est disposée sur la région active et comprend une ouverture et une région isolante ; une seconde couche réfléchissante disposée sur la région d'ouverture ; et une seconde électrode connectée électriquement à la seconde couche réfléchissante. La seconde électrode comprend des première à sixième couches conductrices. La première couche conductrice peut comprendre du Ti, et la sixième couche conductrice peut comprendre de l'Au. 표면발광 레이저소자는 제1 반사층과, 제1 반사층 상에 배치되는 활성영역과, 활성영역 상에 배치되며, 애퍼처 및 절연영역을 포함하는 애퍼처 영역과, 애퍼처 영역 상에 배치되는 제2 반사층과, 제2 반사층과 전기적으로 연결되는 제2 전극을 포함한다. 제2 전극은 제1 내지 제6 도전층을 포함한다. 제1 도전층은 Ti을 포함하고, 제6 도전층은 Au을 포함할 수 있다.
