In waveguide dispersion, refractive index is independent of ______________

In waveguide dispersion, refractive index is independent of ______________ Correct Answer Wavelength

In material dispersion, refractive index is a function of optical wavelength. It varies as a function of wavelength. In wavelength dispersion, group delay is expressed in terms of normalized propagation constant instead of wavelength.
