Patent ID: 8073035

Claim:
A manufacturing method of a surface emitting laser in which a lower reflection minor, an active layer, and an upper reflection minor are successively laminated on a substrate, in which there is formed, in a light emitting section of the upper reflection minor, a structure for controlling reflectance that is configured by a low reflectance region and a convex high reflectance region formed in a central portion of the low reflectance region, and which oscillates at a wavelength of Î», the manufacturing method comprising: forming, when a multilayer film reflection mirror based on a laminated structure formed by laminating a plurality of layers is formed as the upper reflection minor, an absorption layer causing band-to-band absorption in the laminated structure; measuring reflection spectra by irradiating light to the laminated structure after forming the absorption layer and before ending formation of the multilayer film reflection minor; measuring a broad dip wavelength obtained by the measuring of the reflection spectra; and adjusting a thickness of a surface layer of the laminated structure based on the dip wavelength.
