This Letter proposes a scheme for optimizing the signal-to-noise ratio (SNR) of signal to
improve the system performance by a 1? bit delta–sigma modulation (DSM) in a four-mode …

In this paper, we experimentally demonstrated a 2-km high-speed optical interconnection
with pulse-shaped pre-equalized four-level pulse amplitude modulation (PAM-4) signal …

A high-dimensional multi-mode index modulation orthogonal frequency division multiplexing
(HD-MMIM-OFDM) based on geometric shaping is proposed and demonstrated in cost …

Towards higher capacity for the next generation Ethernet in datacenters, transmitting high-
baud-rate signal is necessary. This work presents a band-interleaving receiver with …

Filter bank multi-carrier (FBMC) can provide higher spectral efficiency and lower out-of-band
spectrum leakages than orthogonal frequency division multiplexing (OFDM) or discrete multi …

In this paper, we introduce a simplified digital resolution enhancer (DRE) achieved by
reducing the survived state of the Viterbi algorithm for pre-equalization systems with low …

In intensity modulation direct detection (IM/DD) systems, an adaptively biased layered
optical orthogonal frequency division multiplexing (ABLO-OFDM) scheme is proposed …

We propose a joint look-up-table (LUT)-based nonlinear predistortion and digital resolution
enhancement scheme to achieve high-speed and low-cost optical interconnects using low …

Data center interconnections are cost-sensitive. We propose and demonstrate a cost-
effective C-band intensity modulation direct detection (IM/DD) transmitter for extended range …

In this paper, we experimentally demonstrated a 2-km 100 Gb/s optical interconnection with
pulse-shaped pre-equalized four-level pulse amplitude modulation (PAM-4) signal …
