We report on a 16-nm CMOS DAC based transmitter optimization enabling bitrates up to 1.1 Tb/s. We describe the transmitter optimization and derive the maximization of the net bitrate. Based on back-to-back experiments we optimize the entropy of the p

Heterodyne detection based on a single-ended photodetector is of great interest to simplify the receiver frontend complexity compared to a full coherent one, while retaining the ability of digital chromatic dispersion (CD) compensation. Nevertheless,

We summarize our experimental exploration of the capabilities of an ultrabroad-bandwidth plasmonic Mach-Zehnder modulator (MZM), in an intensity modulation and direct detection (IM/DD) system for short-reach optical transmission up to 10 km. We study

We experimentally test PAM and polybinary modulation in a wide range of symbol rates, as potential candidates to realize next-generation optical lanes. 306-Gbit/s bitrate is demonstrated with 140-GBd PAM-6 signal at sensitivity −17.9-dBm with EDFA-

We report on a SiGe analog multiplexer operating at 128-GSa/s, supporting generation of 63.36-GHz-broad DSCM-PCS-256QAM signal. We successfully achieve net information rate normalized per electrical lane of 2.85-bit/sym/lane back-to-back and 2.81-bit

Distributed data-center networks rely on power and cost-efficient high-speed fiber optical connections over distances up to 80 km which can be densely wavelength-division multiplexed (WDM) in the C-band. Recently, single-sideband (SSB) direct detecti

We demonstrate, to the best of our knowledge, the highest reported single- and multi-channel capacities over a field-deployed data center interconnection (DCI) system operating over 93 km of standard single-mode fiber using only Erbium-doped fiber am

Due to the growing demand for cloud services with high availability, high connection speed and low latency, distributed data-centers have emerged as a key architecture for future optical networks. This architecture relies on power and cost-efficient
