Patent ID: 7924900

Claim:
A manufacturing method of a surface emitting laser in which a lower reflection mirror, an active layer, and an upper reflection mirror are successively laminated on a substrate, in which there is formed, in a light emitting section of the upper reflection mirror, a structure for controlling reflectance that is configured by a low reflectance region and a concave high reflectance region formed in the central portion of the low reflectance region, and which oscillates at a wavelength of λ, the manufacturing method comprising: forming, as the upper reflection mirror, a multilayer film reflection mirror based on a laminated structure; forming, on the multilayer film reflection mirror, a phase adjusting layer which is for reducing the reflectance and which includes an absorption layer causing band-to-band absorption; measuring reflection spectra by irradiating the surface of the phase adjusting layer with light; measuring a broad dip wavelength obtained by measuring the reflection spectra; and adjusting the thickness of the phase adjusting layer based on the dip wavelength.
