Abstract
Inverse-Designed Valley Photonic Waveguides
An inverse design strategy for valley photonic crystals with desired pseudospin states is introduced using transverse spin angular momentum as a design metric. The method automatically tailors pseudospin-dependent band-edge states to realize dual-band waveguides that route light along distinct topological channels depending on frequency, delivering robust, backscattering-immune performance without iterative trial-and-error processes. More details can be found in the Research Article by Yuki Sato, Kenichi Yatsugi, and co-workers (DOI: 101002/adom.202500994).
