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

This paper reviews recent progress on different high-speed optical short-and medium-reach
transmission systems. Furthermore, a comprehensive tutorial on high-performance, low-cost …

We experimentally propose and demonstrate homodyne coherent detection in a short-
distance data center interconnect with bidirectional fiber transmission. The transmitter in the …

We propose a DSP-free coherent-lite system that requires neither high-speed DSP nor high-
resolution signal converters for deployment inside datacenters over single mode fiber links …

The intra-and inter-data center links face continuously increasing pressure on the
transmission capacity while having to meet strict constraints in cost and power consumption …

We report first successful real-time self-homodyne coherent bi-direction transmission
demonstration with 600-Gb/s DP-64QAM under un-cooled~ 7-MHz linewidth DFB laser. A …

We propose and demonstrate bi-directional (BiDi) self-homodyne coherent detection
(SHCD) system experimentally, in which the multiple input multiple output free (MIMO-free) …

Self-homodyne detection (SHD) is a promising approach to realize high-capacity short-
reach optical transmission systems with low cost and low power consumption. We …

We propose and demonstrate an integrated polarization sensing technique by fully
exploiting the adaptive polarization controller (APC) in a self-homodyne coherent (SHC) …

Commonly used 4-level pulse amplitude modulation (PAM-4) scheme limits the amount of
data traffic that can be handled by the PAM-4 based data center interconnects (DCIs) …
