Title (EN) FABRICATION AND APPLICATIONS OF MULTIPLE SIDE-WINDOW, SIDE-FIRING OPTICAL FIBER
(FR) FABRICATION ET APPLICATIONS DE MULTIPLES FIBRES OPTIQUES À ALLUMAGE LATÉRAL ET À FENÊTRE LATÉRALE
Abstract:
(EN) The present disclosure relates to the fabrication and characterization of an optical fiber capable of firing light virtually from any point along its circumferential surface. The optical fiber is preferably prepared by laser micromachining. In preferred embodiments, laser radiation is focused onto a multimode optical fiber axis, forming a conical-shaped cavity (side window) in the fiber core. Because of the total internal reflection when the laser beam reaches the side window-outside medium interface, the beam is reflected to the side of the optical fiber.
(FR) La présente invention concerne la fabrication et la caractérisation d'une fibre optique susceptible d'émettre de la lumière à partir de pratiquement n'importe quel point le long de sa surface circonférentielle. La fibre optique est de préférence préparée par micro-usinage laser. Dans des modes de réalisation préférés, un rayonnement laser est focalisé sur un axe de fibre optique multimode, formant une cavité de forme conique (fenêtre latérale) dans l'âme de fibre. En raison de la réflexion interne totale lorsque le faisceau laser atteint l'interface milieu extérieur-fenêtre latérale, le faisceau est réfléchi sur le côté de la fibre optique.
