英文摘要 | It is necessary to know the zero dispersion wavelength lambda 0, to ensure the reliable transmission of high bit-rate frequency signals via remote transmission paths. The method for determining the zero dispersion wavelength of an optical waveguide knowingly utilizes a disturbing effect that is undesirable in optical communications transmission techniques, which is able to lower the transmission quality. This effect is the so-called four-wave mixing, or in special cases a partially degenerated four-wave mixing. The method couples two light signals of different wavelengths ( lambda 1, lambda 2) into an optical waveguide (4). A mixing product which occurs in the optical waveguide as a result of a partially degenerated four-wave mixing is evaluated by an analyzer (3). The wavelength of one of the two light signals is selectively varied until the optical output of the mixing product reaches a maximum. At that point the wavelength of this light signal coincides with the zero dispersion wavelength lambda 0. |
