Enhancement of Tetrahedral Chromium (Cr<sup>4+</sup>) Concentration for High-Gain in Single-Mode Crystalline Core Fibers
Tetrahedral chromium (Cr<sup>4+</sup>)-ions is the main contributor to gain in the broadband single-mode Cr-doped crystalline core fibers (SCCFs). We have demonstrated a gross gain of 8-dB on a length of 27-cm for a 300-nm broadband SCCF using a thermal annealing technique. Gross gain an...
