Dispersion-decreasing Fibers | previous | next | feedback |
Definition: optical fibers where the chromatic dispersion changes monotonously along the propagation direction
Dispersion-decreasing fibers are optical fibers where the magnitude of the (typically anomalous) chromatic dispersion decreases along the propagation direction. Such a behavior can be obtained e.g. by gradually changing the fiber diameter during the fiber pulling process, because the fiber diameter affects the waveguide dispersion of the fiber.
A possible application of dispersion-decreasing fibers is adiabatic soliton compression, where one exploits the fact that a soliton pulse adapts its parameters (including the pulse duration) to the fiber parameters, provided that the variation of dispersion is sufficiently slow.
