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

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.

A Review of Coherent Optical Communication

MILCOM 1985 - IEEE Military Communications Conference, 1985
Coherent optical communications for fiber transmission media are being seriously considered for both commercial and military applications. A variety of modulation schemes have been examined both in the laboratory and in field trials to verify the feasibility of this transmission technique using optical fibers.
