Abstract: A sol-gel process for producing dry porous metal oxide monoliths, e.g., silica glass monoliths, in which the successive process steps of gelling, aging and drying all occur within a mold formed of a porous non-organic-polymer material, e.g., graphite. The mold is inert to the gel solution and has sufficient strength to withstand the temperatures and pressures encountered during the process. The mold and gel thereby can remain within a sealed autoclave during these process steps, and mechanical handling of the mold and the gel are minimized. This substantially enhances the process' efficiency. Alternatively, the mold can have a non-porous inner skin to enhance ease of cleaning of the mold, and of removal of the gel.

특히, 본 발명의 희토류 원소가 도우프된 석영계 유리는 제조 프로세스 상에 있어서 이 종류의 도우프된 석영계 유리 특유의 결정화를 동반하지 않으므로 투명한 것은 물론 잔류 기포가 없다.
본 발명에 따른 희토류 원소가 도우프된 석영계 유리의 제조방법은 다공질 유리체의 형성 수단과 용액 함침법이 조합된 것이므로 능동적 광소자용으로서, 고순도이고 투명성이 구수하며 희토류원소와 Al이 함께 도우프된 희토류 원소가 도우프된 석영계 유리를 용이하게 제작할 수 있다.

Abstract: The present invention embraces an amplifying optical fiber having a central core adapted to convey and amplify an optical signal and a cladding that surrounds the central core to confine the optical signal conveyed in the central core. The central core is formed of a core matrix in which nanoparticles are present. The nanoparticles themselves include a nanoparticle matrix and rare-earth-dopant elements. The core matrix may also include one or more additional dopants (i.e., in addition to nanoparticles). The amplifying optical fiber possesses a small numerical aperture and is suitable for use in high-pump-power applications without a degraded gain shape.
