Abstract
General rules that describe how to achieve extremely energy-efficient data transmission with oxide-confined VCSELs are derived, explained, and verified by data transmission experiments. We demonstrate that VCSELs with smaller oxide-aperture diameters are more energy-efficient than similar VCSELs with larger oxide-aperture diameters and introduce a new method for analyzing the suitability of different VCSELs for application in different optical interconnect configurations by introducing the modulation factor M. Applying the derived rules for energy-efficient VCSEL operation enables record energy-efficient data transmission with less than 100 femto-Joules per bit in a wide range of bit rates and multimode optical fiber lengths.
