Plasmonic materials, when properly illuminated with visible or near-infrared wavelengths,
exhibit unique and interesting features that can be exploited for tailoring and tuning the light …

We present optical slot antennas and their applications to photonic devices. We show that
metallic nanoslots have the properties of a slot antenna by measuring the transmission …

Phase-change materials (PCMs) have been established as prime candidates for nonvolatile
resonance tuning of nanophotonic components based on a large optical contrast between …

The exponentially decaying nature of evanescent waves renders it difficult to capture, extract
and engineer the wealth of energy and information that they can carry. Utilizing the out‐of …

Owing to their high capacity and flexibility, broadband wireless communications have been
widely employed in radio and microwave regimes, playing indispensable roles in our daily …

In situ refractive index sensors integrated with nanoaperture-based optical tweezers
possess stable and sensitive responsivity to single nanoparticles. In most existing works …

We design and numerically demonstrate an ultracompact plasmonic nanoantenna with
tunable high directionality. The antenna consists of a metallic trimer that can support a highly …

Optical antennas enable efficient coupling between propagating light and bonding
electromagnetic waves like surface plasmon polaritons (SPPs). Under the illumination of …

Optical wireless transmission has recently become a major cutting-edge alternative for on-
chip/inter-chip communications with higher transmission speeds and improved power …

We present an experimental and theoretical study of Babinet's principle of complementarity
in plasmonics. We have used spatially-resolved electron energy loss spectroscopy and …
