Abstract

Abstract

En 中文
• Multi-wavelength NSA method developed for accurate PIQ quantification. • PIQ values validated by amplifier gain simulations. • Y, Yb, and La co-doping reduces ion clustering in L-band EDFAs. • La and Y co-doping enable direct 980 nm pumping of Er 3+ ions. • Rare-earth co-doping improves power efficiency by about 30%.
