WebOct 4, 2024 · Material dispersion is not the only source of dispersion. There is also an effect from the waveguide geometry itself. "Chromatic dispersion" is the combination of the material and waveguide dispersion effects. At some particular frequency, these two effects can cancel each other out giving a wavelength with approximately 0 chromatic dispersion: WebJun 5, 2012 · > An Introduction to Fiber Optics > Pulse dispersion in graded index optical fibers; An Introduction to Fiber Optics.
