Article Synopsis
- The study focuses on accurately characterizing excited-state absorption (ESA) in erbium-doped fibers (EDFs) using a method that combines ON/OFF pumping and a supercontinuum source with a tunable filter.
- By normalizing the ESA profile to its peak value, the researchers facilitate comparisons between samples regardless of their erbium concentration.
- The research also explores how various chemical elements and their concentrations, particularly optimizing aluminum content, can enhance erbium solubility while minimizing negative ESA impacts, aiding in the development of more efficient L-band erbium-doped fiber amplifiers.
Producing high performance amplifiers requires accurate numerical models. As the optimization space is large, computationally efficient models are of great value. Parameter-based models for L-band amplifiers have accuracy limited by difficulty in estimating the Giles-parameter.

To prevent the destruction of the waveguide by the grating formation on the waveguide, we placed a slit mask on the waveguide. By properly adjusting the resonance, this grating can be used as an integrated wavelength filter.
