Dispersion Properties of Bi₂O₃-Based High Nonlinear Optical Fiber

Abstract

The group velocity dispersion of Bi₂O₃-based optical fiber is obtained in optical telecommunication wavelength. The material dispersion of Bi₂O₃-based glass and the waveguide dispersion of Bi₂O₃-based optical fiber are estimated from the wavelength dependence of refractive index. It is shown that Bi₂O₃-based optical fiber exhibits a large group velocity dispersion induced by the strong wavelength dependence of refractive index. The experimental result shows a good agreement with the numerical calculation, indicating that this dispersion analysis on Bi₂O₃-based glass can be applied to the dispersion management of Bi₂O₃-based optical fiber.
