Digital coherent receivers have caused a revolution in the design of optical transmission
systems, due to the subsystems and algorithms embedded within such a receiver. After …

Since the collapse of the market for optical communications equipment at the beginning of
the millennium, there has been diminished interest and investment in technologies for long …

We discuss the generation, wavelength-division-multiplexed (WDM) long-haul transmission,
and coherent detection of 112-Gb/s polarization-division-multiplexed (PDM) 16-ary …

Unlike ultralong coherent optical systems that seriously suffer from fiber nonlinearities, short-
reach noncoherent systems such as data center interconnections, which utilize small, cheap …

(Preliminary): The Orthogonal Frequency Division Multiplexing (OFDM) digital transmission
technique has several advantages in broadcast and mobile communications applications …

This paper describes coherent optical orthogonal frequency division multiplexing (CO-
OFDM) techniques for the long-haul transmission of 100-Gb/s-class channels. First, we …

Quantum-enhanced measurements can provide information about the properties of a
physical system with sensitivities beyond what is fundamentally possible with conventional …

We review and summarize several 100G per channel high-capacity transmission systems
enabled by advanced technologies such as multilevel modulation format, new low-loss and …

We summarize the enabling technologies for photonics-assisted broadband millimeter-wave
(mm-wave) communication, which is a promising candidate for the enhanced mobile …

We experimentally demonstrate 101.7-Tb/s transmission over 355 km spans of standard
single-mode fiber (SSMF) at a net spectral efficiency of 11 b/s/Hz. A total of 370 dense …
