Abstract

Energy-efficient oxide-confined vertical-cavity surface-emitting lasers (VCSELs) emitting at 980 nm, particularly well suited for optical interconnects operating at up to 85°C are presented. The modulation bandwidth f_3dB of our VCSELs increases at low currents with increasing temperature up to 23 GHz at 85°C. The impact of cavity photon lifetime and oxide-aperture diameter on the energy efficiency, temperature stability, and static and dynamic properties of our VCSELs are analyzed. Error-free 40 Gb/s operation at 85°C with an energy-to-data ratio below 100 fJ/bit and a current density close to 10 kA/cm² is predicted based on small signal modulation experiments.
