ABSTRACT: This study presents a detailed exploration of two important areas in contemporary photonics and optical communication technologies: the design and characterization of Er³⁺/Yb³⁺ co-doped bismuth–tellurite glasses for enhanced up conversion luminescence, and the optimization of erbium-doped fiber amplifier (EDFA) performance using an intelligent Adaptive Multi-Stage EDFA Optimization (AMEDO) algorithm. By integrating material engineering with communication system enhancement, the work provides valuable insights for the development of advanced optical devices and networks. In the materials investigation, Er³⁺/Yb³⁺ co-doped bismuth–tellurite glasses were successfully fabricated using the conventional melt-quenching method. Structural and thermal characterization confirmed the amorphous nature of the prepared samples, along with excellent thermal stability and....
