US Classification:

65379, 65393

Abstract:

A method of fabricating a photonic crystal or photonic band gap optical fiber comprises providing a preform that includes a plurality of holes in an outer diameter, wherein the holes extend from a first end of a preform to a second end of the preform, and forming at least one radially inwardly-extending slot within the preform such that the slot intersects at least some of the holes, wherein the slot does not intersect at least one hole. The method also includes establishing a first pressure in the holes intersected by the slot by introducing the first pressure to the slot, and establishing a second pressure in the at least one hole not intersected by the slot by introducing the second pressure to an end of the at least one hole not intersected by the slot. The method further includes drawing the preform into a fiber while independently controlling the first and second pressures.

International Classification:

G01M 11/00

US Classification:

356 731

Abstract:

A method of measuring optical properties of a multi-mode optical fiber during processing of the fiber is described. The method includes: transmitting a light signal through one of the draw end of the multi-mode fiber and a test fiber section toward the other of the draw end and the test fiber section; and receiving a portion of the light signal at one of the draw end and the test fiber section. The method also includes obtaining optical data related to the received portion of the light signal; and analyzing the optical data to determine a property of the multi-mode fiber.
