Plasmonics for extreme light concentration and manipulation.
The unprecedented ability of nanometallic (that is, plasmonic) structures to concentrate light into deep-subwavelength volumes has propelled their use in a vast array of nanophotonics technologiesExpand

Soil Carbon Dioxide Evolution, Litter Decomposition, and Nitrogen Availability Four Years after Thinning in a Japanese Larch Plantation
Abstract Soil carbon dioxide (CO2) evolution, litter decomposition, and nitrogen availability was measured four years after thinning in a 19-year-old Japanese larch (Larix leptolepis Gord.)Expand

Broadband enhancement of light emission in silicon slot waveguides.
We investigate the light emission properties of electrical dipole emitters inside 2-dimensional (2D) and 3-dimensional (3D) silicon slot waveguides and evaluate the spontaneous emission enhancementExpand

General Strategy for Broadband Coherent Perfect Absorption and Multi-wavelength All-optical Switching Based on Epsilon-Near-Zero Multilayer Films
We propose a general, easy-to-implement scheme for broadband coherent perfect absorption (CPA) using epsilon-near-zero (ENZ) multilayer films. Specifically, we employ indium tin oxide (ITO) as aExpand

Optical magnetic mirrors without metals
The reflection of an optical wave from metal, arising from strong interactions between the optical electric field and the free carriers of the metal, is accompanied by a phase reversal of theExpand

Nonresonant enhancement of spontaneous emission in metal-dielectric-metal plasmon waveguide structures
We theoretically investigate the spontaneous emission process of an optical, dipolar emitter in metal-dielectric-metal slab and slot waveguide structures. We find that both structures exhibit strongExpand

Epsilon-near-zero strong coupling in metamaterial-semiconductor hybrid structures.
We present a new type of electrically tunable strong coupling between planar metamaterials and epsilon-near-zero modes that exist in a doped semiconductor nanolayer. The use of doped semiconductorsExpand
