DOI: 10.1002/adfm.202501041

Abstract: Phonon polaritons (PhPs), excitations arising from the coupling of light with lattice vibrations, enable light confinement and local field enhancement, which is essential for various photonic and thermal applications. To date, PhPs with high confinement… read more here.

DOI: 10.1063/1.4981894

Abstract: A band-reject filter working in a near-infrared regime employing a bilayer Ag metasurface was demonstrated numerically and experimentally. This band-reject filter exhibited a broad rejection band (more than 500 nm), simple structure (including an ultrathin metal… read more here.

DOI: 10.1364/ol.478536

Abstract: We experimentally demonstrate the ultrabroadband optical nonlinearity of indium tin oxide nanocrystals (ITO NCs) in the mid-infrared regime. Especially, the ITO NCs show considerable saturation absorption behavior with large modulation depth covering the spectral range… read more here.
