Title (EN) MODE MIXING OPTICAL FIBERS AND METHODS AND SYSTEMS USING THE SAME
(FR) FIBRES OPTIQUES À MÉLANGE DE MODES ET PROCÉDÉS ET SYSTÈMES UTILISANT CELLES-CI
Abstract:
(EN) The present disclosure relates more to mode mixing optical fibers useful, for example in providing optical fiber laser outputs having a desired beam product parameter and beam profile. In one aspect, the disclosure provides a mode mixing optical fiber that includes a core having a refractive index profile; and a cladding disposed about the core. The core of the mode mixing optical fiber supports at least two (e.g., at least five) guided modes at the wavelength. The mode mixing optical fiber is configured to substantially distribute optical radiation having the wavelength propagating therein (e.g., input at its input end or generated or amplified within the core) among a plurality of the guided modes (e.g., to distribute a substantial fraction of the optical radiation having the wavelength propagating therein from its lower-order guided modes to its higher-order guided modes).
(FR) La présente invention concerne en particulier des fibres optiques à mélange de modes utiles, par exemple, pour fournir des sorties laser de fibres optiques présentant un paramètre de produit de faisceau et un profil de faisceau souhaités. Selon un aspect, l'invention concerne une fibre optique à mélange de modes qui comprend un cœur présentant un profil d'indice de réfraction; et une gaine disposée autour du cœur. Le cœur de la fibre optique à mélange de modes prend en charge au moins deux (par exemple au moins cinq) modes guidés à une longueur d'onde donnée. La fibre optique à mélange de modes est conçue pour distribuer sensiblement un rayonnement optique possédant la longueur d'onde se propageant en son sein (par exemple, en entrée à son extrémité d'entrée ou généré ou amplifié dans le cœur) parmi une pluralité des modes guidés (par exemple, pour distribuer une fraction substantielle du rayonnement optique possédant la longueur d'onde se propageant en son sein de ses modes guidés d'ordre inférieur à ses modes guidés d'ordre supérieur).
