What is nanophotonics used for?

The purpose of the science of nanophotonic devices is to synergistically combine the intimate interaction of matter and light at the nanometer scale. Leading areas of research include optical and electronic devices.

What are called Nanophotonics?

Nanophotonics or nano-optics is a part of nanotechnology that investigates the behavior of light on nanometer scales as well as interactions of nanometer-sized objects with light. Nanophotonics often includes metallic components that can transport and focus light through surface plasmon polaritons [108, 109].

What are plasmonic properties?

Plasmonic nanoparticles are particles whose electron density can couple with electromagnetic radiation of wavelengths that are far larger than the particle due to the nature of the dielectric-metal interface between the medium and the particles: unlike in a pure metal where there is a maximum limit on what size …

Why is nanotechnology?

Nanotechnology is hailed as having the potential to increase the efficiency of energy consumption, help clean the environment, and solve major health problems. It is said to be able to massively increase manufacturing production at significantly reduced costs.

What is a photonic relationship?

Platonic love in its modern popular sense is an affectionate relationship into which the sexual element does not enter, especially in cases where one might easily assume otherwise. A simple example of platonic relationships is a deep, non-sexual friendship between two heterosexual people of the opposite sexes.

Is photonics the future?

Photonics – the science of generating, controlling and detecting light – is the future. Light-based technologies can also enhance energy conversion and conservation, lighting and high-quality manufacturing.

What is the meaning of nanophotonics?

Nanophotonics. Nanophotonics or nano-optics is the study of the behavior of light on the nanometer scale, and of the interaction of nanometer-scale objects with light. It is a branch of optics, optical engineering, electrical engineering, and nanotechnology. It often (but not exclusively) involves metallic components,

How can nanophotonics be used to create high peak intensities?

Using nanophotonics to create high peak intensities: If a given amount of light energy is squeezed into a smaller and smaller volume (“hot-spot”), the intensity in the hot-spot gets larger and larger. This is especially helpful in nonlinear optics; an example is surface-enhanced Raman scattering.

What is nano-optic technology?

It often involves dielectric structures such as nanoantennas, or metallic components, which can transport and focus light via surface plasmon polaritons . The term “nano-optics”, just like the term “optics”, usually refers to situations involving ultraviolet, visible, and near-infrared light (free-space wavelengths from 300 to 1200 nanometers).

What is a dipolar source in nanophotonics?

In nanophotonics, strongly localized radiation sources ( dipolar emitters such as fluorescent molecules) are often studied. These sources can be decomposed into a vast spectrum of plane waves with different wavenumbers, which correspond to the angular spatial frequencies.
