Topological nature of non-Hermitian degenerate bands in structural parameter space
Olivia Y. Long, Cheng Guo, Shanhui Fan
In photonics, band degeneracies at high-symmetry points in wavevector space have been shown to exhibit rich physical phenomena. However, obtaining degenerate bands away from such p…

Polarization-independent isotropic nonlocal metasurfaces with wavelength-controlled functionality
Olivia Y. Long, Cheng Guo, Weiliang Jin +1
Flat optics has demonstrated great advances in miniaturizing conventional, bulky optical elements due to the recent developments in metasurface design. Specific applications of suc…
