Oxide-confined 850 nm VCSELs operating at bit rates up to 40 Gbit/s

Abstract
Oxide-confined 850 nm vertical-cavity surface-emitting lasers operating at 40 Gbit/s at current densities ∼10 kA/cm2 are realised. The deconvoluted rise time of the device is below 10 ps and remains hardly temperature sensitive up to 100°C.
