Polarization-selective reconfigurability in hybridized-active-dielectric nanowires. [PDF]
, 2022 Wavelength and polarization are two fundamental properties of light within which information can be encoded and (de)multiplexed. While wavelength-selective systems have widely proliferated, polarization-addressable active photonics has not seen notable ...

Optical Nonlocality in Polar Dielectrics [PDF]
Physical Review X, 2020 Phonon polaritons localized in polar nanoresonators and superlattices are being actively investigated as promising platforms for midinfrared nanophotonics. Here we show that the nonlocal nature of the phonon response can strongly modify their nanoscale physics.
