Coupled experiment/simulation approach for the design of radiation-hardened rare-earth doped optical fibers and amplifiers [PDF]

open access: yes, 2011
We developed an approach to design radiation-hardened rare earth -doped fibers and amplifiers. This methodology combines testing experiments on these devices with particle swarm optimization (PSO) calculations.
