Abstract

Il est décrit des techniques de couplage optique entre une fibre optique et un autre dispositif optique, comme un guide dondes optique planaire ou une région sondée. Une fibre optique pour couplage optique latéral comprend une gaine, un cur disposé dans la gaine, une structure réfléchissante inclinée par rapport à laxe de la fibre, et une structure de convergence de lumière intégrée à la gaine. La structure réfléchissante est configurée pour réfléchir la lumière entre le cur et une voie de couplage latérale qui sétend et qui fournit un couplage optique latéral entre le cur et un extérieur de la fibre. La structure de convergence de lumière à gaine intégrée est configurée pour intercepter et converger la lumière parcourant la voie de couplage latérale. Dans certains modes de réalisation, la fibre optique est une transition de fibre optique couplée entre une fibre optique principale et un autre dispositif optique ou une région sondée. Il est également décrit un système optique couplé comprend une fibre optique couplée à un autre dispositif optique.
