Bismuth-doped optical fibers: a challenging active medium
... and Bi ions emit visible luminescence and no near-IR luminescence.9–12 . The results of many experiments clearly demonstrate that near-IR luminescence is observed because of the reduction of Bi31 ions to a lower oxidation state. Excessive reduction results in the formation of Bi clusters and colloid ...

To characterize the optical performance of the high refractive index Fresnel lens imprinted on a fiber, 660 nm laser light was coupled into the fiber and the focal spot was imaged in immersion oil (n = 1.51) using an oil immersion microscope objective (Nikon 100x, NA=1.3). For comparison, the same m ...
