Patent number: 7650853Abstract: A device for applying, in use, electromagnetic microwave radiation in a plasma cavity. The device includes a plasma cavity present within a housing, being substantially cylindrically symmetric about a first axis, and which plasma cavity includes a cylindrical wall provided with a circumferential slit. The plasma cavity is in communication, via the slit, with a first end of an elongated microwave guide having a longitudinally extending second axis. The device is in communication in use with a microwave generating device via the other end of the microwave guide, in which the electromagnetic microwave radiation being generated may include several modes, where the device can, in use, generate microwave radiation in the slit, which microwave radiation has only one electromagnetic field distribution at least in one direction perpendicularly to the propagation direction of the microwave radiation in the microwave guide.Type: GrantFiled: December 3, 2002Date of Patent: January 26, 2010Assignee: Draka Fibre Technology B.V.Inventors: Mattheus Jacobus Nicolaas Van Stralen, Dennis Robert Simons

Patent number: 7068899Abstract: The present invention relates to a method of manufacturing an optical fiber, which method comprises the following steps: i) providing a hollow substrate tube, ii) passing doped or undoped reactive, glass-forming gases through the interior of the hollow substrate tube, iii) creating such conditions in the interior of the hollow substrate tube that deposition of glass layers onto the interior of the hollow substrate tube takes place, wherein a non-isothermal plasma is reciprocated between two reversal points along the substrate tube, wherein the velocity of movement of the plasma decreases to zero at each reversal point, iv) collapsing the substrate tube thus obtained so as to form a solid preform, and v) drawing an optical fiber from said solid preform. In addition to that, the present invention relates to a preform for manufacturing an optical fiber, as well as to an optical fiber.Type: GrantFiled: May 17, 2004Date of Patent: June 27, 2006Assignee: Draka Fibre Technology B.V.Inventors: Igor Milicevic, Frans Gooijer, Eric Aloysius Kuijpers, Dennis Robert Simons, Rob Hubertus Matheus Deckers
