mode dispersion
1mode dispersion — noun (telecommunications) In optical fibre communications, distortion of individual signals, caused by different modes of propagation of the light inside the fibre • • • Main Entry: ↑mode …
2Polarization mode dispersion — (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical… …
3Dispersion — may refer to: In physics: The dependence of wave velocity on frequency or wavelength: Dispersion (optics), for light waves Dispersion (water waves) Acoustic dispersion, for sound waves Dispersion relation, the mathematical description of… …
4Dispersion (optics) — This article is about dispersion of waves in optics. For other forms of dispersion, see Dispersion (disambiguation). In a prism, material dispersion (a wavelength dependent refractive index) causes different colors to refract at different angles …
5Mode (statistics) — In statistics, the mode is the value that occurs most frequently in a data set or a probability distribution.[1] In some fields, notably education, sample data are often called scores, and the sample mode is known as the modal score.[2] Like the… …
6Mode-locking — is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10−12 s) or femtoseconds (10−15 s). The basis of the technique is to induce a fixed phase… …
7Dispersion-shifted fiber — (DSF) is a type of optical fiber made to optimize both low dispersion and low attenuation. Dispersion Shifted Fiber is a type of single mode optical fiber with a core clad index profile tailored to shift the zero dispersion wavelength from the… …
8Dispersion (Glasfaser) — Dispersion ist in der Optik die Abhängigkeit der Ausbreitungsgeschwindigkeit von Wellen von ihrer Wellenlänge λ. Die Ausbreitungsgeschwindigkeit des Lichts wird durch die Brechzahl n beschrieben. Verwendet man nun Wellenpakete, die gemäß der… …
9Mode Sifflement — Le mode sifflement est un mode de propagation dispersif dans les plasmas magnétisés. Excité par la foudre, des perturbations, se propagent dans la magnétosphère d un hémisphère à l autre de la Terre. Son caractère dispersif provoque un étalement… …
10Dispersion (biologie) —  Ne doit pas être confondu avec Distribution spatiale (écologie). Certaines graines très légères se laissent emporter par le vent, parfois sur de grandes distances. Il s agit souvent d espèce …
