Abstract:
1. A method of fabricating an optical fiber or an optical device, comprising the steps of: forming a partially-sintered fine structure in a base material for fabricating the optical fiber or the optical device; soaking the partially-sintered fine structure in a doping solution, which contains a reducing agent and a doping ion selected from the group consisting of a metal ion, a rare earth ion, and a mixture thereof, for a selected duration; drying the partially-sintered fine structure after having been soaked in the doping solution; and heating the partially-sintered fine structure after drying such that the doping ion is reduced, directly or indirectly, by the reducing agent and the partially-sintered fine structure is sintered, wherein the reducing agent is at least one selected from the group consisting of glucose, sucrose, glycerin, dextrin, benzene, phenol, hexane, toluene, styrene, naphthalene, TEOS (tetraethyl orthosilicate), TMOS (tetramethyl orthosilicate), TEOC (tetraethyl orthocarbonate), and TMOC (tetramethyl orthocarbonate).
