An Optical Fiber Communication System Based on Coherent Modulation. Part 1.

Abstract

Coherent optical communication systems have potential application possibilities which make them a very interesting research area. Compared to present optical communication systems operating at 1.3 micron or 1.55 micron they can operate with 20 dB's increase in receiver sensitivity which allows around 100 km increase in repeater separation for point to transmission systems. In addition fully developed coherent systems will allow multiplexing and demultiplexing of several hundreds of information channels all transmitted via just one single mode fiber. Keyworkds include: Coherent optical communications systems, Semiconductor lasers, Frequency stabilisation, Modulation of amplitude-frequency and phase, Injection locking, Single mode optical fibers, Polarisation properties and Dispersion properties.
