ABSTRACT:
A method for mitigating modal dispersion in a multimode optical fiber involves launching a diffractionless optical beam, such as a Bessel beam, into a multimode optical fiber. A fiber optical transmission system includes a multimode optical fiber transmission medium having an input end and an output end, an optical signal transmitter in communication with the input end of the multimode optical fiber medium, means for converting the optical signal into a diffractionless optical signal, means for launching the diffractionless optical signal in the input end of the multimode optical fiber transmission medium, means for outputting the propagated optical signal from an output end of the multimode fiber transmission medium, and a receiver that receives the optical signal from the output means. Fiber optic communication systems employing the invention embodiments include point-to-point transmission links, local area networks and WDM systems including coarse wavelength division multiplexing and dense wavelength division multiplexing systems.
