英文摘要	A method of manufacturing a surface-emitting laser element having a light-emitting mesa structure with an emitting area including a high-reflectance portion and a low-reflectance portion includes forming a layered body that includes a lower reflecting mirror, a cavity structure, and an upper reflecting mirror on a substrate; forming a first area on an upper surface of the layered body; forming a second area having the same size as the first area on the upper surface of the layered body; forming a light-emitting mesa structure and a monitoring-mesa structure by etching the first area and the second area, respectively; forming a confinement structure including a current passage area surrounded by an oxide in the light-emitting mesa structure and the monitoring-mesa structure; and measuring the size of the current passage area of the monitoring-mesa structure.
