Patent ID: 8361817

Claim:
A method for manufacturing a surface-emitting laser device that emits laser light in a direction perpendicular to a substrate, the method comprising: manufacturing a laminated body in which a lower reflecting mirror, a resonator structure including an active layer, and an upper reflecting mirror including a to-be-selectively-oxidized layer are laminated on the substrate; etching the laminated body from an upper surface thereof to form a mesa structure having at least the to-be-selectively-oxidized layer exposed at a side surface thereof; and mounting the laminated body on a tray having a front surface thereof shaped to follow a warpage of the laminated body at an oxidation temperature and selectively oxidizing at the oxidation temperature the to-be-selectively-oxidized layer from the side surface of the mesa structure, thereby generating a confinement structure in which a current passing region is surrounded by an oxide.
