Plasmonics is a rapidly developing field at the boundary of physical optics and condensed matter physics. It studies phenomena induced by and associated with surface plasmons—elementary polar excitations bound to surfaces and interfaces of good nanostructured metals. This Roadmap is written collectively by prominent researchers in the field of plasmonics. It encompasses selected aspects of nano...

The emerging field of plasmonics has yielded methods for guiding and localizing light at the nanoscale, well below the scale of the wavelength of light in free space. Now plasmonics researchers are turning their attention to photovoltaics, where design approaches based on plasmonics can be used to improve absorption in photovoltaic devices, permitting a considerable reduction in the physical th...

Metal-based plasmonics has a wide range of important applications but is subject to several drawbacks. In this paper, we propose and investigate an all-semiconductor-based approach to plasmonics in mid-infrared (MIR) wavelength range using InAs heterostructures. Our results show that InAs heterostructures are ideal for plasmonics with the shortest plasmon wavelength among common semiconductors....

We present a three-dimensional finite difference time domain (FDTD) method on graphics processing unit (GPU) for plasmonics applications. For the simulation of plasmonics devices, the Lorentz-Drude (LD) dispersive model is incorporated into Maxwell equations, while the auxiliary differential equation (ADE) technique is applied to the LD model. Our numerical experiments based on typical domain s...

Plasmonics publishes peer-reviewed articles that both advance and report on the knowledge and practice of the interactions of free-metal electrons, Plasmons. Coverage includes theory, physics, and applications of surface plasmons in metals, and rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. The journal covers the theory, synthesis and optical proper...

Metamaterials and plasmonics are powerful tools for unconventional manipulation and harnessing of light. Metamaterials can be engineered to possess intriguing properties lacking in natural materials, such as negative refractive index. Plasmonics offers capabilities of confining light in subwavelength dimensions and enhancing light-matter interactions. Recently, the technological potential of gr...

Ge-on-Si has been demonstrated as a platform for Si foundry compatible plasmonics. We use laser thermal annealing to demonstrate activated doping levels >1020 cm-3 which allows most of the 3 to 20 μm mid-infrared sensing window to be covered with enhancements comparable to gold plasmonics.

Plasmonics-active gold nanostars exhibiting strong imaging contrast and efficient photothermal transduction were synthesized for a novel pulsed laser-modulated plasmonics-enhanced brain tumor microvascular permeabilization. We demonstrate a selective, optically modulated delivery of nanoprobes into the tumor parenchyma with minimal off-target distribution.

Here we benchmark different photonic interconnect technology options and contrast them to hybridization assuming plasmonics (photonics) for active (passive) elements, respectively. Our results show superior latency and power consumption performance for hybridization. OCIS codes: (200.4650) Optical interconnects, (250.5403) Plasmonics, (230.0250) Optoelectronics, (250.5300) Photonic integrated c...
