Abstract
Une fibre optique multicoeur est fournie et comprend une gaine et de multiples coeurs disposés dans la gaine. Chaque coeur possède un guide lumineux et suit une trajectoire hélicoïdale selon l'axe de la fibre. La fibre multicoeur comprend également un ensemble de zones de couplage latéral discrètes, qui sont distribuées de manière longitudinale et azimutale selon l'axe de la fibre. Chaque zone de couplage latéral forme un guide de couplage optique qui permet au moins une entrée et une sortie latérales de la lumière entre une paire correspondante d'un des coeurs et un extérieur de la fibre multicoeur. Un système de sonde optique pour transmettre ou capter la lumière d'une région sondée est aussi fourni. Le système de sonde optique comprend une fibre optique multicoeur qui permet le couplage de la lumière guidée hors des coeurs pour sa transmission à la région sondée ou au captage de la lumière dans la région sondée pour le couplage vers l'un des coeurs.
