Large aperture 850 nm VCSELs operating at bit rates up to 25 Gbit/s

Journal article, 2008

Small signal modulation bandwidths in excess of 20 GHz are demonstrated for a 9 μm oxide aperture VCSEL emitting at 850 nm. Open eye diagrams are obtained under large signal modulation at bit rates up to 25 Gbit/s with a bias current density of only 10 kA/cm2.
