摘要： The disclosed method of making a mixed glass optical fiber exemplarily comprises providing a high-silica tube, and causing molten non-high silica glass to flow into the bore (12) of the tube by application of a pressure differential. In order to prevent cracking, the tube desirably has an outer diameter/inner diameter ratio of at least 5, preferably about 10 or even more, and an inner diameter of at most 1 mm. In a preferred embodiment, a conventional SiO 2 tube is partially collapsed to an inner diameter less than 1 mm, a quantity of a non-high-silica glass is placed in a neck of the partially collapsed tube and heated such that molten glass communicates with the reduced-diameter portion of the bore and can be drawn into the reduced-diameter portion by means of a vacuum. The resulting mixed glass body is then further stretched to result in a core rod of core diameter at most 0.3 mm. After overcladding the core rod with SiO 2 , fiber is drawn from the thus produced preform. A thus produced fiber with SiO 2 cladding and SiO 2 -Al 2 O 3 -La 2 O 3 -Er 2 O 3 core was used as an optical fiber amplifier and provided high gain.

摘要： Die Herstellung von Substratrohren aus Quarzglas umfasst typischerweise einen Verfahrensschritt, bei dem ein einen Außendurchmesser C a , einen Innendurchmesser C i und eine Innenbohrung aufweisender Quarzglas-Hohlzylinder kontinuierlich in einer Heizzone bereichsweise erweicht und zu einem Rohrstrang mit einem Außendurchmesser T a und einem Innendurchmesser T i abgezogen wird. Durch Ablängen des Rohrstrangs werden Substratrohre der gewünschten Länge erhalten. Sie dienen als Halbzeug bei der Herstellung von Vorformen für optische Fasern. Das werkzeugfreie Umformen des Ausgangs-Hohlzylinders bereitet Probleme bei der Einhaltung der nominalen radialen Abmessungen des Rohrstrangs und der Rotationssymmetrie. Insbesondere bei starken Verformungsgraden werden Durchmesserschwankungen sowie Ovalitäten und Wandeinseitigkeiten beobachtet. Um eine kostengünstige Herstellung von Substratrohren mit hoher Maßhaltigkeit und Oberflächenqualität zu gewährleiten, schlägt die Erfindung eine Modifikation des bekannten Verfahrens vor, bei dem für Hohlzylinder und Rohrstrang gelten: C a > 180 mm, C r > 3 mit C r = C a /C i , T r r = T a /T i und C i /T i

摘要： The invention is a method of making an optical fiber or cane (600) that has optical properties that vary axially. Core glass (100) and clad glass (200) are fed into a furnace to form the cane or fiber. The velocities of the feeding of the clad and core are controlled so that the total combined mass per unit time is constant. The diameter of the core (604) varies along the length of the fiber or cane in accordance with the control of the velocities. The variance in the core diameter results in the variance of the axial optical properties of the fiber or cane.
