In a single mode optical fiber , the zero dispersion wavelength is the wavelength or wavelengths at which material dispersion optics dispersion and waveguide dispersion cancel one another. In all silica based optical fiber s, minimum material dispersion occurs naturally at a wavelength of approximately 1300nm. Single mode fibers may be made of silica based glasses containing dopants that shift the material dispersion wavelength, and thus, the zero dispersion wavelength, toward the minimum loss window at approximately 1550nm. The engineering tradeoff is a slight increase in the minimum attenuation coefficient . Such fiber is called dispersion shifted fiber . Another way to alter the dispersion is changing the core size and the refractive indices of the material of Fiber optics Principle of operation core and Cladding fiber optics cladding . Because fiber optic materials are already highly optimized for low scattering and high transparency alternative ways to change the refractive index were investigated. As a straight forward solution tapered fiber s and holey fiber s or photonic crystal fiber s PCF were produced. Essentially they replace the cladding by air. This improves the contrast of refractive indices by a factor of 10. Therefore the effective index is changed, especially for longer wavelengths. This type of refractive index change versus wavelength due to different geometry is called waveguide dispersion . As these narrow waveguides 1 3 m core diameter are combined with ultrashort pulse s at the zero dispersion wavelength pulses are not instantly destroyed by dispersion. After reaching a certain peak power within the pulse the non linear refractive index starts ... is also used, more loosely, in multi mode optical fiber .

Single wavelength anomalous dispersion abbreviated SAD is a technique used in X ray crystallography that facilitates the determination of the structure of proteins or other biological macromolecules by allowing the solution of the phase problem . In contrast to multi wavelength anomalous dispersion , SAD uses a single dataset at a single appropriate wavelength. One advantage of the technique is the minimization of time spent in the beam by the crystal, thus reducing potential radiation damage to the molecule while collecting data.
