Structural colors are colors generated by the interaction between incident light and
nanostructures. Structural colors have been studied for decades due to their promising …

Dielectric and metallic gratings have been studied for more than a century. Nevertheless,
novel optical phenomena and fabrication techniques have emerged recently and have …

To move beyond colorant-based pigmentation display technologies, a variety of photonic
and plasmonic crystal based structures have been designed and applied as colour filters …

We demonstrate experimentally a periodic array of differently-sized and circularly-shaped
gap plasmon resonators (GPRs) with the average absorption~ 94% for unpolarized light in …

Recent advances in low‐dimensional materials and nanofabrication technologies have
stimulated many breakthroughs in the field of nanophotonics such as metamaterials and …

We demonstrate numerically that metal-insulator-metal (MIM) configurations in which the top
metal layer consists of a periodic arrangement of nanobricks, thus facilitating gap-surface …

We perform a comprehensive analysis of multi-band absorption by exciting magnetic
polaritons in the infrared region. According to the independent properties of the magnetic …

In this paper, an all-metal nanostructure is designed with a large frequency ratio (∼ 6) and a
large bandwidth ratio (∼ 32), and consists of period slit-box cavities and nanodisk clusters. It …

Highly nonlinear optical materials with fast third-order nonlinear optical response are crucial
for the operation of all-optical photonic devices, such as switches for signal processing and …

Thin films made of metallic nanoparticles can exhibit strong photothermal effects (PPE) on
near-infrared light irradiation, paving a way for new designs of spectrally selective building …
