Abstract
We experimentally investigate the mode power distribution from long spans of graded-index multimode fiber. We find that, at relatively low powers, linear random mode coupling leads to a Bose-Einstein mode distribution. At powers near the nonlinear soliton regime, the distribution approaches a modified Rayleigh-Jeans law.| File | Dimensione | Formato | |
