proposed scheme designed to reconstruct a complex-valued signal from the measurement …

Modern communication systems rely on efficient quadrature amplitude modulation formats
that encode information on both the amplitude and phase of an electromagnetic carrier …

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 …

The Kramers-Kronig (KK) receiver is capable of retrieving the phase information of optical
single-sideband (SSB) signal from the optical intensity when the optical signal satisfies the …

The Kramers-Kronig (KK) receiver has recently drawn a great deal of attention due to its
capability of retrieving the phase information from the directly-detected intensity waveforms …

Photonic reservoirs are machine learning based systems that boast energy efficiency and
speediness. Thus they can be deployed as optical processors in fiber communication …

We propose a low-complexity digital implementation of the Kramers–Kronig receiver and
analyze its performance and complexity. In simulations and experiments, we find that a …

We present a new receiver scheme that recovers complex-valued QAM modulated data
while using two separate branches of direct detection. It seamlessly integrates dispersion …

This chapter focuses on various high-capacity direct-detection (DD) systems, which include
conventional intensity-modulation and direct-detection (IM-DD) systems that have been …

We propose two transceiver schemes based on Kramers-Kronig (KK) detection. One targets
low-cost high-throughput applications and uses pulse amplitude modulation (PAM) …
