摘要

We present the first true voltage -mode VCSEL driver achieving 60 Gbit/s at peak efficiency of 0.36 pJ/bit with BER < le-12 improving the state-of-the-art by a factor of 2. Transmission experiments showcase error-free 56 Gbit/s transmission up to 100 m fiber. Advanced demonstration enables even 224 Gbit/s when using SWDM at a total efficiency of 0.4 pJ/bit.
