Abstract
We investigate the influence of oxide aperture size on the performance of intracavity contacted oxide-aperture vertical-cavity surface-emitting lasers with asymmetric current injection. Several counteracting mechanisms are shown to result in size dependent behavior, which limits the performance of very small cavities. Reducing the oxide aperture is shown to improve the threshold current and the 3dB bandwidth. However, significant increase of optical losses is observed that is attributed to increase the threshold current density and to decrease the maximum output power. From the far-field measurement, we have shown that the smaller aperture VCSELs have large FWHM. Also, we have achieved the small signal modulation bandwidth of 10.3GHz with 4.5μm oxide aperture diameter at 9mA bias current.
