Abstract
An electrically pumped, long-wavelength VCSEL includes a long wavelength active region having electrical contacts on opposed sides thereof. A layer of semiconductor material is included in the active region having an electrically conductive portion defining a lasing aperture and current confinement volume with the conductive portion being limited by an electrically insulating portion. Windows are formed in the electrical contacts in alignment with the lasing aperture and mirror stacks are positioned on the long wavelength active region in each of the windows. At least one of the mirror stacks includes a metamorphic distributed Bragg reflector for heat conduction.
