Oxide-relief vertical-cavity surface-emitting lasers with extremely high data-rate/power-dissipation ratios

By using oxide-relief technique, a high modulation-efficiency (9.8GHz/mA
^1/2
) and a high modulation-speed (34 Gbps) with a record-high data-rate/power-dissipation ratios (2.9 (9.2) Gbps/mW at 34 (12.5) Gbps) of 850nm VCSELs have been demonstrated.
