An apparatus for forming an optical fiber device comprising at least one optical fiber includes a mold having a forming surface, a heating source for heating the mold or the optical fiber, and an insert defining at least one optical fiber locator passage for guiding at least one optical fiber toward the forming surface. A method for forming an optical fiber device from at least one optical fiber includes the steps of heating the optical fiber or a forming surface of a mold to a temperature greater than a melting temperature of the optical fiber; advancing the optical fiber into contact with the forming surface of the mold such that a portion of the optical fiber is formed into a shape inversely corresponding to a shape of the forming surface; and withdrawing the optical fiber from the forming surface.
