Coherent optical communication

International Zurich Seminar on Digital Communications, Electronic Circuits and Systems for Communications., 2002
Activities associated with the development of coherent optical communication systems for application in future public broadband networks are reviewed. It is pointed out that the main future transmission medium, the optical single-mode fiber, provides an extremely high bandwidth which will have to be utilized when high-capacity-demanding digital ...

Communication modes with partially coherent fields

Journal of the Optical Society of America A, 2007
We develop a theory for the description of partially coherent wave fields in linear optical systems in terms of the so-called communication modes. The communication modes are the singular functions and singular values of the appropriate propagation kernels.

Hierarchical coherent and non-coherent communication

2017 51st Asilomar Conference on Signals, Systems, and Computers, 2017
In this paper, we propose a method for simultaneous communication of coarse and detailed information over three types of layers: two nested layers to be communicated non-coherently using Grassmannian constellations and an additional layer to be communicated coherently using unitary constellations.

Communication before coherence

European Journal of Neuroscience, 2012
AbstractThe hypothesis of communication through coherence proposes that coherent or synchronous oscillations in connected neural systems can promote communication. It has been applied mainly to how oscillations interact in connected networks. We tested by simulations whether information transmission about an external stimulus from one network to a ...

Quantum communication with coherent states

IEEE Transactions on Information Theory, 1989
Quantum communication is studied under the cutoff-rate criterion for transmission of M coherent states of real amplitude (M=2, . . ., 7). Comparison with other measurement operators of interest, such as the number and the quasi-classical operators, is made. The effect of quantization of the decision level on the cutoff rate is considered. >
