We report 50 Gbit/s modulation capability using four silicon micro ring modulators within a footprint of 500 µm2. This is the highest total modulation capability shown in silicon using compact micro-ring modulators. Using the proposed techniques, silicon nanophotonic bandwidths can meet the requirements of future CMOS interconnects by using multiple wavelengths to extend beyond single device speeds.

  19. Silicon carrier dispersion modulators are ultimately limited by the carrier saturation velocity, due to free carrier–optical phonon interactions. In silicon, optical phonons limit the maximum speed of carriers to 10 ps per micron of transit length, which limits the maximum bandwidth to ~100 Gbit/s for a typical transverse carrier transit distance of 1 micron.
