An investigation is reported of the visible and near-infrared upconversions in Tm 3+/Yb 3+ co-doped double-clad silica fibers (TYDFs) under excitation at 980nm. The TYDFs used were fabricated using the modified chemical vapor deposition (MCVD) and solution doping techniques. Three distinct upconvers...
