Abstract
Dispersion is reduced in a graded index optical fiber having a finite number of core layers by introducing slow longitudinal variations into the thickness of each layer. The thickness of each layer varies between maxima and minima, the latter being proximate to zero.
Claims6
A graded index optical fiber having decreased optical dispersion comprising a core member and a cladding surrounding said core member, said core member including a plurality of layers, the refractive indices of which radially decrease from a maximum at the center of the fiber, characterized in that
- the thickness of each of said layers has spatial fluctuations along the longitudinal axis of said fiber, said fluctuations occuring slowly, the thickness of each layer varying between maximum and minimum values with the minimum thickness of each of said layers being proximate to zero.
