    Abstract: A process for producing a glass member includes subjecting a silicon, boron, phosphorous or aluminum compound or both a silicon, boron, phosphorous or aluminum compound and a dopant compound to vapor phase reaction to form a fine powder of fused silica, borate, phosphate or alumina or doped fused silica, borate, phosphate or alumina. Then the powder is partially sintered to form a porous glass body which subsequently is immersed in a solution containing a dopant compound thereby depositing the dopant compound on the surfaces of the pores in the glass body. Thereafter, the porous glass body is dried before the pores are collapsed to form the glass member.

    Abstract: Procedures are disclosed for producing both core-cladding optical fibers and self-focusing optical fibers from porous germinate and/or silicate glasses obtained after phase separation and removal of the soluble phase. A glass which is separable into at least two phases one of which is soluble, is heated to cause phase separation. The soluble phase is leached out removing undesired impurities. The pores are collapsed and this glass is used to produce cores and/or cladding layers, or self focusing fibers. According to one aspect of the invention, preforms of the porous glass have their interconnected pores stuffed with a dopant. In the production of core-cladding optical fibers, the dopant modifies the index of refraction of the core and/or cladding so that the index of refraction of the core is greater than that of the cladding. The control of this index of refraction can be accomplished by addition of non silicate network formers such as GeO.sub.2 to the original melt before phase separation. These network formers will stay in the insoluble phase. In producing self-focusing fibers, the dopant may be non-uniformly deposited in order to produce a radial gradient in the index of refraction, or sodium or potassium ions may be ion exchanged into the glass for a portion of a dopant containing lithium or thallium to produce such an index of refraction gradient.
