• Erbium-doped silica-based glass for optical amplifiers is fabricated from silica powders by a compression-forming method using a cold isostatic pressing (CIP) technique. Silica powders are prepared from slurry containing fumed silica with submicrometer diameter and erbium source by granulating using a spray drier. The average diameter of the granulated powders is 50μ and about 150 times as large as that of the fumed silica. The silica powders are packed in a rubber mold and are compressed by CIP. It is found from thermal analysis that the compressed powders can be degreased PVP at 600℃. After degreasing at 600℃, the compressed powders are sintered by a sintering process using an electric furnace or a gas burner. The compressed powders can be vitrified by using not the electric furnace but the gas burner. The existence of Er ions in the glass sintered by the gas burner is confirmed from UV-VIS spectra.
