Control of the soliton self-frequency shift dynamics using topographic optical fibers

Opt Lett. 2013 Sep 1;38(17):3390-3. doi: 10.1364/OL.38.003390.

Abstract

We demonstrate that the dynamics of the soliton self-frequency shift can be accurately controlled by using tapered optical fibers with optimized longitudinal profile shape (that we term topographic fibers). The tapering profiles tailored for a targeted soliton spectral trajectory through dispersion and nonlinearity management are determined by an inverse algorithm. This control is demonstrated experimentally with topographic photonic crystal fibers fabricated directly on a drawing tower.
