A vapor-phase axial deposition system (5) for fabricating a lightguide soot boule (16). The system (5) is comprised of a short cylindrical housing (10) having end plates (26－26) affixed thereto. A starting member (58) is radially directed into the central portion of the housing (10) and a torch (12)

A vapor-phase axial deposition system (5) for fabricating a lightguide soot boule (16). The system (5) is comprised of a short cylindrical housing (10) having end plates (26－26) affixed thereto. A starting member (58) is radially directed into the central portion of the housing (10) and a torch (12) is activated to direct a stream of glassy soot thereat. The member (58) is simultaneously rotated and withdrawn from the housing (10) as a cylindrical, porous, soot boule is formed on the end thereof. The housing (10) having a substantially two-dimensional character eliminates secondary gas flow within the housing (10) resulting in enhanced deposition rates and repeatability.

A method of fabricating a substantially cylindrical lightguide soot boule in a vapor-phase axial deposition system, comprising: projecting a stream of soot, formed in a flame, in a first plane, towards a deposition portion of a forming cylindrical soot boule, the axes of the boule and the soot strea

A method of fabricating a substantially cylindrical lightguide soot boule in a vapor-phase axial deposition system, comprising: projecting a stream of soot, formed in a flame, in a first plane, towards a deposition portion of a forming cylindrical soot boule, the axes of the boule and the soot stream being in a first plane; and confining the first plane between first and second planar surfaces, the distance between said planar surfaces being sufficiently close so as to substantially eliminate flame flicker and wander during the formation of the soot boule.
