摘要： A method is provided for making a photonic band gap fiber including the steps of etching a preform and then drawing the preform into a photonic band gap fiber. Glass tubes are bundled and then formed into a photonic crystal perform having a number of passageways by reducing the cross-section of the bundle. One of the passageways is enlarged by flowing an etchant through it. After cleaning, the band gap fiber is made from the etched photonic preform, for example, by drawing.

摘要： A method and device for providing an optical fiber secondary preform by collapsing an over-cladding tube on an optical fiber primary preform is disclosed in the present invention. The device for over cladding the optical fiber primary preform includes a hand bar as a first supporter for supporting the optical fiber primary preform, which hand bar has a sealing-up part of the over-cladding tube on an outer diameter part thereof and also includes a supporting handle tube as a second supporter for supporting the over-cladding tube, which the purity of the supporting handle tube is different from that of the over-cladding tube. Also the supporting handle tube includes a ring to make it equal two centers of the optical fiber primary preform and the over-cladding tube.

摘要： The invention involves fabricating a ceramic tube, e.g., a silica overcladding tube, with very little bow, e.g., about 0.3 mm per meter or less. In particular, the invention involves securing the tube by a handle that both allows the tube to hang plumb during treatment, and also is capable of deforming during such heat treatment to maintain the plumb arrangement.

摘要： The invention relates to a method of assembling two optical fiber preforms together end-to-end, the method comprising the following operations: the two cylindrical preforms are placed in alignment along a common longitudinal axis; the preforms are rotated about the common longitudinal axis; the facing ends of said preforms are heated by a heater; and the preforms are moved towards each other parallel to the common axis to press them against each other so as to form intimate contact between the ends after cooling. According to the invention, the heating is performed by causing the preforms or heater to move in a radial direction orthogonal to the common longitudinal axis in such a manner as to heat the peripheries and then the cores of said preforms.

摘要： In a known method for the manufacture of a tube made of a vitreous material, especially of quartz glass, a hollow cylindrical semifinished product made of a vitreous material is carried essentially vertically to a heating zone, wherein it is heated and drawn off downwards—without the use of tools—to the tube by forming a transitional area from semifinished product to tube, while diameter and wall thickness of the tube are continuously measured, and the tube's measured geometrical data being used to generate a control signal with the aid of which a pressure difference is regulated between pressure P1 in the interior space of the semifinished product, the transitional area and the tube, as well as pressure P2 in the heating chamber which is regulated in the heating zone at least in the transitional area from semifinished product to tube and its adjacent tube area. This method is to be developed further so as to enable the processing of a broader spectrum of hollow cylindrical semifinished products to tubes with the desired inside and outside dimensions. This task is solved according to the invention such that for the manufacture of tubes with the ratio of their outside diameter (DRa) to their inside diameter (DRi) being greater than the ratio of the outside diameter (DHa) to the inside diameter (DHi) of the semifinished product—pressure P1 in the inside space of the semifinished product, the transitional area and the tube being kept at a value which is smaller than the value of pressure P2 in the heating chamber, with pressure P1 being maintained by means of a suction (vacuum) pump.
