  • Publication number: 20250076577
    Abstract: Provided are an apparatus and method for manufacturing an optical wire. The apparatus includes a wire forming module configured to form an optical wire for optically coupling a first point to a second point, an image acquisition module configured to acquire an image of the optical wire, a curing module configured to cure the optical wire, and a control module. The control module checks a shape and position of the optical wire through the image acquired by the image acquisition module and outputs a control signal to the curing module so that ultraviolet (UV) light is emitted to the optical wire.

  • Patent number: 11002571
    Abstract: The present invention relates to a method of fabricating a nanowire connected to an optical fiber, the method comprising the steps of: a) filling a micropipette with a material solution to form a nanowire; b) coaxially aligning the micropipette with the optical fiber at one end of the optical fiber such that a longitudinal axis of the optical fiber and a longitudinal axis of the micropipette are aligned in a line; c) forming a meniscus of the material solution to form the nanowire in the coaxially aligned state; and d) fabricating the nanowire by evaporating a solvent from the material solution to form the nanowire while lifting the micropipette in a state in which the meniscus is formed, in a direction away from the optical fiber. The method further comprises a step of a step of controlling a shape of the distal end of the nanowire by irradiating a laser to the nanowire fabricated.
