Dispersion management in highly nonlinear, carbon disulfide filled holey fibers

Abstract

We study various fiber designs which incorporate a highly nonlinear liquid, carbon disulfide, with the aim of designing a structure with the highest possible nonlinearity and at the same time a low and flattened dispersion at telecom wavelengths, as required for many all-optical processing devices. We observe that soft glass-based fibers cannot fully exploit the high nonlinearity of carbon disulfide, whereas a silica microstructured fiber with a selectively filled core allows excellent dispersion control and a nonlinear coefficient in excess of 6500 W-1km-1 at telecoms wavelengths
