Towards integrated transmitters for short-reach optical links in the C-band

In this talk, we will review our recent demonstrations of novel transmitter structures employing Si or III-V integration for inter data center links. We will in particularly look at how the effect of group-velocity dispersion in the C-band can be circumvented in multi-(OFDM) and single-carrier (PAM4) modulation formats thanks to specially designed transmitter architectures.
