Abstract

Recent evolution in nanoscience and nanotechnologies has brought novel possibilities in the development of optical fibers. Dual-wavelength fiber lasers have attracted scientific attention due to their prospective applications in fields including next-generation optical fiber communication, ranging systems, and spectroscopy. Nanostructurization has shown itself as a suitable method for preparing fiber lasers operating simultaneously at dual wavelengths. We report on the design of nanostructured or “pixelated” core fabricated by assembling erbium- and ytterbium elements, as well as on the optimization of the average concentration of rare earth elements using numerical modeling. Preliminary experimental results of erbium- and ytterbium-doped nanostructured-core fiber will be presented.
