摘要： A method for fabricating tapered optical fibers is provided. The method includes applying thermal energy at a location defined along an elongated length (114, 116, 118) of an optical fiber (112). The method also includes varying the location in a first direction of travel at a predetermined rate along the elongated length of the optical fiber while applying a tension to the optical fiber. The method further includes removing the tension when the location is outside a first portion (116) of the elongated length. According to an aspect of the invention, the method includes transitioning from the first direction of travel to a second direction of travel opposed to the first direction of travel when the location is within a second portion (114) of the optical fiber. The method further includes transitioning from the second direction of travel to the first direction of travel when the location is within a third portion (118) of the optical fiber.
