Investigation on the interplay between dispersion and nonlinearity in subwavelength-diameter silica fibers

摘要

A theoretical study of optical properties of subwavelength-diameter silica fibers is presented, with an emphasis on the interplay between dispersion and nonlinearity. The normalized dispersion and effective nonlinearity are used to analyze the diameter-dependent relative strength at all wavelengths. The dispersion and nonlinearity length are calculated for guiding waveguide dimension design for possible applications.
