What is nanophotonics?

nanotechnology photonics

Nanoscience/nanotechnology: creation of useful/functional materials and devices through control of matter on the nanometer length scale and exploitation of novel phenomena and properties at that length scalePhotonics is the technology and science of light generation, handling and control

Nanophotonics is the interface between the two with optical materials patterned on wavelength-size scales or smaller.

Self-assembly

MBE

sputtering

Plasma etching:RIE,ICP

AFMSEM

TEMPECVD

plasmonics modulators

switches

Add/drop filters

X-ray lithography

Left-handed materials

Photonic crystals

Nanophotonics: defined by its applications • communications technology• lasers• solid-state lighting• data storage• lithography• (bio-)sensors• optical computers• solar cells• light-activated medical therapies • displays• smart materials

Nanophotonics is a unique part of physics/chemistry/materials science because it combines

a wealth of scientific challenges with a large variety of near-term applications.

Large interest from industry infundamental research on nanophotonics

Examples of Nanophotonics

• Iridescent colors on butterfly wings are due to Photonic-Crystals. i.e. Stacks of Nanoscale Gratings

Metal Nanoparticles Enhance Raman Scattering Signals by several orders of magnitude

This Effect is called Surface Enhanced Raman Scattering (SERS)

Bioimaging with NanoparticlesNanoparticles are also used for bioimaging by non-optical techniques like Magnetic Resonance Imaging (MRI), Radioactive Nanoparticles as tracers to detect drug pathways or imaging by Positron Emission Tomography (PET), and Ultrasonic Imaging. For MRI, the magnetic nanoparticles could be made of

oxide particles which are coated with some biocompatible polymer.Newer Nanoparticle Heterostructures have been investigated which offer the possibility of imaging by several techniques simultaneously. An example is Magnetic Quantum Dot.
