Coherent optical communications using coherence-cloned Kerr soliton microcombs [PDF]

open access: yesNature Communications, 2022
Kerr frequency combs are a promising laser source for future optical networks. The authors demonstrate coherence-cloning between two remote Kerr combs and improve optical coherent communication in terms of performance, power consumption, and simplicity.

Coherent optical communications

open access: yesOptical Fiber Communication, 1985
Coherent optical communication systems became possible with development of the gas laser in the early 1960s. During the decade following development of the laser, Enloe and Rodda showed homodyne detection to be possible when they successfully phase-locked two gas lasers.

Coherent communication with linear optics [PDF]

open access: yesPhysical Review A, 2008
We show how to implement several continuous-variable coherent protocols with linear optics. Noise can accumulate when implementing each coherent protocol with realistic optical devices. Our analysis bounds the level of noise accumulation. We highlight the connection between a coherent channel and a nonlocal quantum nondemolition interaction and give ...

Binary Communication with Gazeau–Klauder Coherent States

open access: yesEntropy, 2020
We investigate advantages and disadvantages of using Gazeau−Klauder coherent states for optical communication. In this short paper we show that using an alphabet consisting of coherent Gazeau−Klauder states related to a Kerr-type nonlinear ...
