| Description |
In this work, a new erbium (Er) doped nano-engineered scandium-phospho-yttria-alumina-silica (SPYAS) glass-based optical fiber is reported, fabricated through the MCVD process, and solution doping technique, followed by a suitable thermal annealing of pristine preform. The fabrication process comprises the incorporation of erbium doped phase-separated scandium-yttria rich crystalline nanoparticles into the core region through in situ process based on phase-separation and crystal growth phenomena. The material characterization results, obtained from transmission electron microscopy, electron diffraction pattern, energy dispersive X-ray, electron probe micro analysis, and X-ray fluorescence, confirm the formation of Er2O3 doped crystalline phase-separated scandium-yttria rich nanoparticles in the core region. The formation of scandium-ultra rich nano-crystalline environment, possessing low photon energy around the erbium ions, enhanced the fluorescence intensity. Such kind of nano-engineered glass reduces the noise figure around 4.35dB, and provides broadband optical flat gain with an average value of 38.675dB, varied by less than +/- 0. 7dB spanning over a broad wavelength region of 1530-1590nm compared to the pristine and Sc free Er-doped fibers. Such kind of nano-engineered glass based Er doped fiber will be useful for making highly efficient optical amplifiers, suitable for present broadband optical communication systems.
