Abstract :
The spatial transient regime of a fiber mode transformation near the cutoff frequency is analyzed both theoretically and numerically depending on material losses and radial distribution of the refractive coefficient of a guiding structure. Kerr-like nonlinearity of a fiber material is shown to be efficiently used to manage the transmittance of the structures near the cutoff frequency of a fiber mode
