Coherent Optical Communication

Asia Optical Fiber Communication and Optoelectronic Exposition and Conference, 2008
Optical coherent receivers with subsequent DSP show great promise as enabling technologies for ultra-high information rate optical transmission systems. DSP alleviates the need to lock the phases of the LO and transmitter signal, which is one of the limiting factors for the use of coherent receivers in the optical domain.

Scheme of coherent optical chaos communication

Optics Letters, 2020
We propose and numerically demonstrate a scheme of coherent optical chaos communication using semiconductor lasers for secure transmission of optical quadrature amplitude modulation (QAM) signals. In this scheme, a laser intensity chaos and its delayed duplicate are used to amplitude-quadrature modulate a continuous-wave light to generate a chaotic ...

Coherent Optical Communication

Seventh Topical Meeting on Integrated and Guided-Wave Optics, 1984
Virtually all fibre transmission systems up to the present have used simple intensity modulation of the transmit laser, most frequently in the form of binary ON/OFF modulation. At the receiver, incoming optical power has been converted directly to photocurrent in a photodetector.

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 ...

Coherent fiber-optic communications (review)

Soviet Journal of Quantum Electronics, 1985
This review is devoted to heterodyne and homodyne methods for the transmission and reception of data along single-mode fiber waveguides. The advantages of the coherent data transmission methods over the currently used methods of modulation of light intensity and direct detection are demonstrated.
