Abstract
A torch for fabricating optical fiber preforms may include a body having a surface and two or more slit-shaped orifices oriented parallel or substantially parallel to each other along the surface. The torch body may further include two or more conduits connected to corresponding orifices. The torch may be used by orienting it relative to a preform substrate, and simultaneously emitting two or more gases from corresponding orifices toward the surface of the preform substrate, such that the gases are involved in a reaction to form a soot.

A torch for fabricating optical fiber preforms, comprising:
- a torch body having a surface and a plurality of slit-shaped orifices on the surface, each slit-shaped orifice having a longitudinal axis, a first end, and a second end, the slit-shaped orifices oriented substantially parallel to each other at the first ends, a central slit-shaped orifice of the plurality of slit-shaped orifices having a straight longitudinal axis, at least two of the plurality of slit-shaped orifices located on opposing sides of the central slit-shaped orifice and having curving longitudinal axes diverging away from the central slit-shaped orifice and from each other toward the second ends, the torch body further including a plurality of conduits, a proximal end of each conduit coupled to a different one of the slit-shaped orifices, wherein each of the slit-shaped orifices increases in width from its first end to its second end.
