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. |
