Webwhere v is the normalized frequency, defined as Eq. (1.15) and γ is a measure of the asymmetry of the cladding refractive indices. Once the wavelength of the light signal and the geometrical parameters of the waveguide are determined, the normalized frequency v and γ are determined. Therefore u, w, w′ and ϕ are given by solving the eigenvalue equations … WebAll waveguide systems are operated in a frequency range that ensures that only the lowest mode can propagate. If several modes can propagate simultaneously, one has no control over which modes will actually be carrying the transmitted signal. This may cause undue amounts of dispersion, distortion, and erratic operation. A mode with cutoff ...
