| titleOfInvention |
Optical waveguide for fibre-optic amplifier for wavelengths around 1550 nm |
| abstract |
According to the invention, the course of the fluorescence band of optical fibers doped with erbium and aluminum can be flattened further if the core contains fluorine as an additional dopant, e.g. in the form of ErF₃ and AlF₃.n n n Application: Optical fiber amplifier with flattened gain profile. |
