Dispersionless Single-Mode Lightguides With α Index Profiles

Abstract

By means of a numerical solution to Maxwell's equations, we calculate those parameters necessary to design and fabricate single-mode lightguides. These include optimum core radius and profile parameter α. In the design the dispersion is minimized by varying the core radius while the relative index difference Δ, the wavelength λ and profile parameter are held fixed. A comparison of calculated dispersion with experimental data shows excellent agreement
