Abstract
Based on the exact solution of the Maxwell’s equations, the group velocity dispersion characteristics of micro/nano optical fibers near 2-μm wavelength have been studied numerically. The results show that the micro/nano optical fiber has large normal dispersion near 2-μm wavelength by carefully choosing the core size. For air-clad micro/nano optical fiber with core size 900 nm, the group velocity dispersion can be up to 3318.78  ps 2 /km . By introducing a thin dielectric layer, the maximum dispersion can be adjusted by varying the thickness and refractive index of the dielectric layer.
