Title (EN) OPTICAL FIBER OF WHICH AT LEAST ONE OF THE END FACES COMPRISES A CONVEX-PLANE MICROLENS COUPLED AGAINST SAID END FACE
(FR) FIBRE OPTIQUE DONT AU MOINS L"UNE DES FACES D"EXTREMITES COMPORTE UNE MICROLENTILLE PLAN-CONVEXE ACCOLEE PAR SA FACE PLANE CONTRE LADITE FACE D"EXTREMITE
Abstract: front page image
(EN)An optical fiber of which at least one of the end faces comprises a convex-plane microlens coupled by the plane face thereof against said end face. Said optical fiber is a multimode fiber (2) having a core with a diameter of at least about ten micrometers, and said microlens is a dome-shaped lens (5) made of transparent thermoplastic material, the plane face (5a) of this microlens having an extension at least equal to the cross-section of the fiber core. Application, in particular, to light injection into optical fibers.
(FR)Une fibre optique dont au moins l"une des faces d"extremite comporte une microlentille plan-convexe accolee par sa face plane contre ladite face d"extremite. Ladite fibre optique est une fibre multimode (2) ayant un coeur presentant un diametre d"au moins environ une dizaine de micrometres, et ladite microlentille est une lentille en forme de calotte spherique (5) faite en un materiau thermoplastique transparent, la face plane (5a) de cette microlentille presentant une extension au moins egale a la section transversale du coeur de la fibre. Application notamment a l"injection de lumiere dans les fibres optiques.
