Abstract
A glass article is manufactured in which a doping agent is incorporated into a porous glazed structure constituting a matrix with communicating pores, by immersing this matrix in a solution containing the doping agent or dopant within the matrix and the solvent (and if necessary the decomposition products) is removed from the matrix after which the latter is heated until causing the collapse of the pores and the production of a homogeneous continuous structure, the precipitation of the dopant within the matrix being carried out without appreciable evaporation of the solvent, and the matrix, after precipitation of the dopant, being subjected to a controlled drying operation with a view to eliminating the solvent, thereby producing a suitable distribution of the dopant within the glass article. Optical waveguides of the graded-index type may thus be produced.
