The central idea of the project is the use of the modal spectrum of the optical fibers in order to take profit of the particular properties of specific high-order modes. This subject lies within the context of developing high capability optical communications by exploiting space division multiplexing techniques, few mode fibers and multi-core fibers. The design of an optical fiber permits to obtain modes whose properties (dispersion, modal area, intensity distribution) are very different from the ones of the fundamental mode. Individual excitation and propagation of these modes make feasible the use of these properties in different applications related but not restricted to communications, such as lasers, amplifiers, special light sources (supercontinuum, photon pairs, frequency combs, etc.), sensors and optical switches
