A method of making a microlensed fiber by splicing a doped silica rod to an optical fiber and shaping the end of the doped silica rod into a plano-convex refracting lens. The doped silica rod has a lower melting point and annealing point than undoped silica, and therefor less power is required to manufacture the microlensed fiber. This decreases wear to the heating elements of the manufacturing equipment and therefor increases the number of microlensed fibers that can be manufactured between cycles. A further aspect of the present invention is a microlensed fiber made by the above process.
