Dispersion compensation in coherent fiber-optic communications

Optics Letters, 1987
Linear filtering techniques in coherent communications systems appear to offer a useful method for increasing the bandwidth in dispersion-limited fiber-optical signal propagation. These techniques are described, and the requirements on filter performance are outlined. Bandwidth is shown to be related to the square root of the filter figure of merit.

Coherent Optical Communication Systems

2011
The rapid evolution of long-haul optical communications systems, witnessed in the last five years, is due to the gradual adoption of spectrally efficient, multilevel modulation formats, in conjunction with polarization division multiplexing (PDM) and coherent intradyne detection assisted by digital signal processing (DSP).

Coherent optical space communications

2006
This paper reviews the present state of concepts and technologies of coherent optical space communications. Emphasis is placed on the receiving segment. Heterodyne and homodyne reception allows to realize sensitivities close to the theoretical limits which amount to as little as 10 to 40 photons per bit.
