| 英文摘要 | A vertical cavity surface-emitting laser (VCSEL) and a method of fabricating the same with easier alignment of a light output side aperture and an oxide aperture, The VCSEL includes: lower and upper reflection layers laminated with each other and forming a longitudinal resonance section there between; an active layer for producing a laser beam, an electrode formed in a ring shape on the upper reflection layer so the electrode has an aperture through which the laser beam is projected; a contact layer formed on the upper reflection layer; a ¼ wavelength layer formed on the contact layer such that a high transmittance area with the highest transmittance for the laser beam is formed within the aperture of the electrode; and a dielectric layer covering the contact layer and the ¼ wavelength layer, except for the electrode formed part. |
