Multiring optical fibers doped with Tm3+ and Ho3+ for broadband profiled emission near 2µm
A silica Large Mode Area double-clad optical fiber, fabrication and characterization is presented. The multiring doping profile with Tm<sup>3+</sup> and Ho<sup>3+</sup> ions with an undoped silica structure was used to obtain the emission of eye-safe wavelengths ranging from 1710 to 2100nm. EPMA analysis confirmed maximum Tm<sub>2</sub>O<sub>3</sub> and Ho<sub>2</sub>O<sub>3</sub> complex weight concentrations of 0.46% and 0.53%, respectively. The luminescence profile is investigated across fiber lengths ranging from 2 to 6m, revealing a decrease in full width at half maximum (FWHM) from 423nm to 367nm. The fiber design is optimized for single-mode operation near 2μm, making it highly suitable for a range of applications in photonics devices.
