Bandwidth analysis of the principal states superimposed from vortex modes propagating in an optical fiber

摘要

The wavelength dependence of the principal states of transmission in multimode fibers is analyzed using a group theoretical analysis. We expand our principal states analysis modes propagating in an optical fiber in a basis of optical vortices for super dense optical networks to include the wavelength width over which these states are valid. The theory is formulated using SU(N) group theory and eigen analysis to determine the modal expansion coefficients. To first order, the principal states are frequency and wavelength independent; however dependencies develop away from which the frequencies of the specific expansion coefficients are determined.
