Nonlinear Effectsmplification is only valid if the optical field strength is rather low. Hence, the intensity has to be small. This is the case for noncoherent light sources such as lamps, light emitting diodes, and sunlight. Since the invention of the laser, a light source that delivers coherent light with extremel

FWM is comparable to the so called intermodulation in electrical communication systems. This effect was already mentioned in th

From the bow a water wave was initiated, reaching over the entire channel width. Russell followed the wave at the river bank with his horse and notice

The spontaneous Raman scattering was discovered, long before the invention of the laser, in the year 1924 by the Indian physicist Sir Chandrasekhara Raman (knighted 1929).

In order to reduce costs and to increase reliability, signal processing should be carried out in the optical domain in future optical transport networks. This is mainly due to two reasons; with increasing bi
