Coherent Optical Sources for Communications [PDF]
The development of coherent optical sources, producing usable amounts of power, has provided a stimulus for communications research. Coherent sources in the form of lasers and parametric oscillators are available at wavelengths which span the entire optical spectrum.

Coherent communication with linear optics [PDF]
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 ...

Coherent optical frequency combs: From principles to applications
A coherent optical frequency comb is a kind of broad-spectrum light sources delivering equidistant frequencies, and correspondingly its temporal waveform appears as a sequence of ultrashort pulses.

Coherent optical communications using coherence-cloned Kerr soliton microcombs
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
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.
