Regular modes in a mixed-dynamics-based optical fiber

Michel, Claire Allgaier, Markus Doya, Valérie

A multimode optical fiber with a truncated transverse cross section acts as a powerful versatile support to investigate the wave features of complex ray dynamics. In this paper, we concentrate on the case of a geometry inducing mixed dynamics. We highlight that regular modes associated to stable periodic orbits present an enhanced spatial...

Singular modes management in highly multimode fibers with a non standard geometry

Doya, Valérie Allgaier, Markus Legrand, Olivier

Si les fibres optiques multimodes à section transverse non circulaire constituent des laboratoires d'études privilégiés pour sonder les manifestations ondulatoires du chaos des rayons, ces dernìères conf èrent des propriétés singulìères aux modes de propagation. Nous montrons comment le contrôle des modes dans des fibres hautement multimodes...
