Driven primarily by cloud service and data-center applications, short-reach optical
communication has become a key market segment and growing research area in recent …

The recently reported high spectral efficiency (SE) and high-baud-rate signal transmission
are all based on digital coherent optical communications and digital signal processing …

Quantum key distribution (QKD) generates symmetric keys between two remote parties and
guarantees the keys are not accessible to any third party. Wavelength-division multiplexing …

We demonstrate ultra-dense SDM transmission of 360-channel Super-Nyquist-WDM DP-
QPSK signals over 9.8-km 6-mode 19-core fiber, achieving the record fiber capacity of 2.05 …

In this paper, a joint digital signal processing (DSP) scheme including partial response
sha** and trellis coded modulation (TCM) technology is proposed to mitigate the …

High-speed millimeter-wave (mm-wave) wireless transmission at 40 Gb/s or higher will be
required in the near future. Due to bottleneck in electrical devices, mm-wave wireless signal …

We summarize the enabling technologies for photonics-assisted broadband millimeter-wave
(mm-wave) communication, which is a promising candidate for the enhanced mobile …

We experimentally demonstrated 140-Gb/s transmission over 20-km standard single-mode
fiber employing pulse-amplitude modulation (PAM)-4 and direct detection (DD) at 1.3 μm …

Ultra-dense spatial-division multiplexing (SDM) is achieved by mode multiplexed technique
with multiple cores in a single fiber, namely few-mode multi-core fiber. Using a 9.8-km six …
