Complex rare-earths doped optical waveguide |
摘要 |
The present invention relates to a complex rare-earths doped optical waveguide. In particular, the complex rare-earths doped optical waveguide in accordance with an embodiment of the present invention is for modifying emission spectrum of erbium that is able to obtain gain from shorter wavelength than 1530 nm. A complex rare-earths doped optical wavelength is provided. The complex rare-earths doped optical waveguide in accordence with an embodiment of the present invention includes clad and core. The core is doped with erbium (Er) ion. The internal or surface of the core is doped with at least one complex rare-earth ions. The internal and the surface of the core is distanced by certain length from center of the core.
