Beyond 300Gb/s from an integrated single-channel silicon photonics modulator driver combination

We investigate the performance boundary of integrated CMOS silicon photonics transmitters by using optical equalisation techniques. Without using any off-line DSP techniques at the receiver side, experimental results demonstrate 182Gbps OOK and 308Gbps PAM-4 transmissions with the energy efficiency including driver, of better than 1pJ/bit.
