  • Abstract
    Long-wavelength InAlGaAs VCSELs with Al2O3 embedded current-confinement structures are reported. Using atomic layer deposition, the current confinement structures are fabricated by depositing Al2O3 on airgap surfaces of undercut apertures, which are formed by laterally etching the active region. 1.57 μm VCSELs showing an output power of over 1 mW and direct modulation characteristics at 4 Gbit/s are reported using these current-confinement apertures.
