Simulation results of the spatial current distribution in the active region of VCSELs with various double-current-aperture configurations. The inset shows a schematic cross section of the apertures and current flow.
Simulation results of the carrier-density profiles for three different VCSEL designs. The insets show the dominant transverse optical modes for each design.
Cw and pulsed lasing spectra from three different VCSEL designs at a current injection that is three times the threshold. The active regions of these devices are approximately in diameter.
Spectral linewidth vs -aperture size for VCSEL designs A and B. The left inset shows the cw light output versus current for design B and the right inset shows a near-field image at peak power for design B.
Comparison of different designs.
