Abstract
Dramatic improvements in the performance of vertical-cavity surface-emitting lasers (VCSELs) have been achieved in structures utilizing oxidized Al layers for electrical and optical confinement. Wall-plug efficiencies in excess of 50%, and 9 μA threshold currents have been demonstrated from such structures. Modulation bandwidths of up to 14 GHz have been demonstrated previously from implantation-defined VCSELs. This work demonstrates that oxide-confined VCSELs also have excellent high-speed modulation properties, with record modulation bandwidths in excess of 16 GHz, indicating their promise for application in data transmission links.
