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 …

The performance of high-speed intensity modulation direct detection (IM-DD) transmissions
is severely degraded by the linear inter-symbol interference (ISI), due to both bandwidth …

Simple high-speed optical transmission technologies are desired for use in intra-and inter-
datacenter networks. In this study, we demonstrate simple single-carrier intensity-modulated …

Systems modulating, transporting, and detecting lightwaves have evolved tremendously in
the past four decades. The first systems, which were relying on intensity modulation with …

The use of advanced modulation formats helps to reduce the number of components
required for short reach optical communication modules at 100 Gb/s and beyond. Unlike …

Intensity modulation and direct detection (IM/DD) together with pulse amplitude modulation
(PAM) is a cost-efficient solution for intra-datacenter links. However, sophisticated digital …

Intensity modulation with direct detection (IM/DD) provides a low-cost solution for data center
optical interconnects. To achieve higher data rate, Tomlinson-Harashima precoding (THP) is …

In this work, we compare 4-pulse amplitude modulation and on–off keying modulation
formats at high speed for short-range optical communication systems. The transmission …

We report on a 116 Gb/s on-off keying (OOK), four pulse amplitude modulation (PAM) and
105-Gb/s 8-PAM optical transmitter using an InP-based integrated and packaged externally …
