ABSTRACT:
A monomode optical transmission fiber with a tapered end portion. A lens is arranged on the end portion. The lens has a refractive index higher than that of the fiber core. Such a fiber has a substantially better coupling efficiency from a diode laser into the fiber core. The lens can be formed by immersing the tapered end portion of the fiber in a transparent liquid material. The drop formed on the end portion of the fiber after withdrawal from the liquid solidifies into a lens.
