Paper Abstract

980 nm VCSELs based on sub-monolayer growth show for 20 Gbit/s large signal modulation clearly open eyes without adjustment of the driving conditions between 25 and 120 °C. To access the limiting mechanism for the modulation bandwidth, a temperature dependent small signal analysis is carried out on these devices. Single mode devices are limited by damping, whereas multimode devices are limited by thermal effects, preventing higher photon densities in the cavity.
