Multimode optical fibers have recently regained a strong interest in particular because of their ability to deliver a quasi-Gaussian beam profile after nonlinear spatial clean-up of a multimode optical guided wave at high intensity. Indeed, a speckled beam obtained at the end of a multimode fiber in linear propagation regime can be transformed into a quasi-single- mode pattern at high input power.

Abstract
Multimode optical fibers have recently regained a strong interest in particular because of their ability to deliver a quasi-Gaussian beam profile after nonlinear spatial clean-up of a multimode optical guided wave at high intensity. Indeed, a speckled beam obtained at the end of a multimode fiber in linear propagation regime can be transformed into a quasi-single- mode pattern at high input power.| File | Dimensione | Formato | |
