Abstract:
An electrically pumped, long-wavelength vertical cavity surface emitting laser comprising:a long wavelength active region having opposed major sides with a first electrical contact on one of the major sides and a second electrical contact on another of the major sides; at least one layer of material included in the long wavelength active region and having an electrically conductive portion defining a lasing aperture and current confinement volume, the electrically conductive portion being limited by an electrically insulating portion; a first window in the second electrical contact in alignment with the lasing aperture and a first mirror stack positioned on the long wavelength active region in the first window; a second window in the first electrical contact in alignment with the lasing aperture and a second mirror stack positioned on the long wavelength active region in the second window, one of the first mirror stack and the second mirror stack including a first metamorphic distributed Bragg reflector; and a contact metal in electrical interaction with the second electrical contact and in thermal interaction with the first distributed Bragg reflector mirror stack.
