Spatiotemporal mode decomposition of ultrashort pulses in linear and nonlinear graded-index multimode fibers

Mario Zitelli et al.

Summary: We developed a spatiotemporal mode decomposition technique to analyze the power distribution of ultrashort pulses in graded-index multimode fibers. Our findings reveal that the power content of beam modes in the dispersive pulse propagation regime follows the Bose-Einstein law, which is a result of power diffusion from mode coupling. In the soliton regime, the output mode power distribution approaches the Rayleigh-Jeans law.
