Abstract:
1. A method of making an optical fiber, the method comprising: assembling a plurality of elongate elements to define an elongate void; using a deposition technique to form within the void a material contacting at least some of the elements while maintaining the elongate void; and drawing a preform, including the assembly of elongate elements, into an optical fiber, wherein the deposition technique is selected from the group consisting of: forming the material in situ from a vapour or liquid phase; forming the material with a chemical vapour deposition process; forming the material with a thermal chemical vapour reaction; forming the material by forming a soot and sintering the soot; forming the material with a liquid phase deposition; forming the material by providing a sol, allowing the sol to gel, and firing the gel; and forming the material by providing a liquid material and setting the material.
