Maximum information transfer rates in fiber-optic waveguides
Abstract
The information transfer characteristics of single-mode and low-mode fiber-optic waveguides are investigated. A method for the compensation of material dispersion by waveguide dispersion of the opposite sign is developed. It is shown that sandwich waveguides can provide for this type of compensation in the entire wavelength range utilized, while two-layer quartz-base waveguides can provide for compensation only at wavelengths exceeding 1.3 micron. In the case when the total first-order dispersion is equal to zero, an analysis is presented of Gaussian pulse expansion; the optimal duration of the pulse at which the information transfer rate is maximal is determined.
