Abstract
In an optical network through which data is transmitted as a stream of bits during successive bit periods by an optical source with a given optical center frequency, to a receiver for detecting a frequency baseband, interferometric noise power, in particular incoherent beat noise power, is minimized by causing a variation in the center frequency of the source such as to cause a redistribution of the incoherent beat noise power from the baseband to higher frequencies, thereby reducing the noise in the baseband.
