| 摘要 |
The invention relates to a family of erbium-doped fluorophosphate glasses for use in optical signal amplification and which are doped, for 100 parts by weight constituted by:with up to 10 parts by weight of erbium oxide.The glasses according to the present invention exhibit a high gain and very flat spectrum over the 1550 nm bandwidth. These glass compositions are particularly well suited for use in fiber or planar optical amplification in WDM and similar applications.
