This paper reviews the foundations of the Kramers–Kronig (KK) receiver, a recently
proposed scheme designed to reconstruct a complex-valued signal from the measurement …

Coherent detection empowers optical receivers the capability of recovering the optical field
propagating through the fiber. Field recovery not only increases the degree of freedom for …

In this paper, we review in detail experimental demonstrations of Kramers–Kronig (KK)
based direct detection systems with high per-carrier interface rates, high spectral …

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 …

Optical access networks are playing a more critical role in providing diverse emerging
applications for human-and machine-type communications. With the ever-growing demand …

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 …

Since its early commercial deployment in the late 1980s, optical fiber has evolved to become
the predominant carrier of the globe's communications. Yet, after accommodating the world's …

Data centers, the engines of the global Internet, rely on powerful high-speed optical
interconnects. In optical fiber communication, classic direct detection captures only the …

Due to the growing demand for cloud services with high availability, high connection speed
and low latency, distributed data-centers have emerged as a key architecture for future …

Phase retrieval (PR) schemes based on modified Gerchberg-Saxton (GS) algorithm using
pilot symbol or pilot tone have recently attracted great attentions in self-coherent systems. In …
