In recent years, short-reach optical links have attracted much more attention and have come
to constitute a key market segment due to the rapid development of data-center applications …

Unlike ultralong coherent optical systems that seriously suffer from fiber nonlinearities, short-
reach noncoherent systems such as data center interconnections, which utilize small, cheap …

In this paper, transmission performances of directly modulated laser (DML), electro-
absorption modulated laser (EML) and Mach-Zehnder modulator (MZM) are experimentally …

In the past decade, China has made great investments in studying photonics and
photocommunication with larger communication capacity, better performance, and lower …

In this paper, we propose adaptive channel-matched detection (ACMD) to effectively
compensate channel distortions for C-band 64-Gbit/s intensity-modulation and direct …

We report on what is to the best of our knowledge the longest 50-Gb/s/λ O-band wavelength-
division multiplexed (WDM) transmission. A pair of in-house built bismuth-doped fiber …

This paper proposes a nonlinear equalization technique enabled by long short-term memory
(LSTM) recurrent neural networks. The proposed technique is implemented at the end of …

In this letter, transmission of directly-modulated PAM-4 in C-band is experimentally
demonstrated. Instead of introducing any optical devices for dispersion management, we …

We present the design and optimization of the optical single side-band (SSB) Nyquist four-
level pulse amplitude modulation (PAM-4) transmission using dual-drive Mach-Zehnder …

We experimentally demonstrate the transmission of 100 Gbit/s and beyond vestigial
sideband (VSB) n-level pulse amplitude modulation (PAM-n) signals, with a commercial 10 …
