Happy to share our preprint on AAA rational approximation for photonic fibers doi.org/10.48550/arX...! We show how to compute only the fundamental modes within a dense spectrum of nonrelevant modes. Many thanks to my colleagues @cnoatzib.bsky.social, @zuseinstitute.bsky.social, @jcmwave.bsky.social!
