Transceiver imperfections become the primary source of impairment as baud rate and
modulation order grow in advanced optical coherent communications. Thus, transceiver …

High-symbol-rate coherentoptical transceivers suffer more from the critical responses of
transceiver components at high frequency, especially when applying a higher order …

We propose a novel digital pre-distortion (DPD) based on neural networks for high-baudrate
optical coherent transmitters. We demonstrate experimentally that it outperforms an …

High throughput coherent optical transmitters are key components in future optical
communication infrastructure. However, these transmitters are often distorted with the …

This tutorial paper reviews advanced modulation techniques that have been proposed in the
literature for the implementation of flexible (or reconfigurable) transceivers, which are …

For a future 5G Ethernet-based fronthaul architecture, 100G trunk lines of a transmission
distance up to 10 km over a standard single-mode fiber (SSMF) in combination with cheap …

Digital pre-compensation (DPC) is an indispensable block of state-of-the-art optical
transceivers, and a key enabler for high-order modulation formats (HOMFs) transmission. A …

We propose an autoencoder (AE)-based transceiver for a wavelength division multiplexing
(WDM) system impaired by hardware imperfections. We design our AE following the …

A self-calibration procedure for an optical transmitter is provided. During the self-calibration
procedure, a phase bias of an optical modulator of the optical transmitter is set so that an in …

We present a digital predistortion (DPD) technique to compensate for in-phase and
quadrature (IQ) Mach-Zehnder modulators (MZM) with finite extinction ratio (ER). The …
