The design of application-specific integrated circuits (ASIC) is at the core of modern ultra-
high-speed transponders employing advanced digital signal processing (DSP) algorithms …

In the evolution of optical networks, spectral efficiency (SE) enhancement has been the most
cost-efficient and thus the main driver for capacity increase for decades. As a result, the …

Optical interconnects (OIs) based on vertical-cavity surface-emitting lasers (VCSELs) are the
main workhorse within data centers, supercomputers, and even vehicles, providing low-cost …

We propose a novel digital pre-distortion (DPD) based on neural networks for high-baudrate
optical coherent transmitters. We demonstrate experimentally that it outperforms an …

200-Gb/s per lane intensity-modulation (IM) direct-detection (DD) optics are being
commercialized to support 800G and 1.6 T applications inside datacenters. Though IM-DD …

High-symbol-rate coherentoptical transceivers suffer more from the critical responses of
transceiver components at high frequency, especially when applying a higher order …

Neuromorphic photonics aims to transfer the high-bandwidth and low-energy credentials of
optics into neuromorphic computing architectures. In this effort, photonic neurons are trying …

Optical transmission links are generally composed of optical fibers, optical amplifiers, and
optical filters. In this paper, we present a channel reconstruction method (CRM) that extracts …

One promising and competitive solution to keep up with the rapid growth in data traffic while
at the same time addressing increasing network cost, is the efficient reuse of legacy optical …

Abstract A record 2.11-Tb/s/wavelength net bitrate by optimizing entropy and code rate of
176-GBd PCS144QAM was generated with a> 130-GHz-bandwidth InP-DHBT in-house …
