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 …

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 …

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 …

The amount of data center traffic is rapidly increasing, and it is necessary for short-reach
optical transmission such as Ethernet to realize a higher capacity data link. Therefore, the …

Theoretically, for continuous signals, Kramers-Kronig (KK) receivers should be able to
precisely reconstruct a band-limited signal's phase from its envelope if the minimum phase …

We propose a novel method to reconstruct the optical signal phase information using direct
detection. The method is suitable for minimum phase signals and it enables low complexity …

Rapid increase of data-center traffic due to the growing use of cloud services and mobile
broadband services requires a higher capacity Ethernet link based on an economical …

In this paper, the theoretical bit error rate (BER) of N-level pulse amplitude modulation (PAM-
N) and M-ary quadrature amplitude modulation (M-QAM) have been studied and compared …
