Plasmonics is a new technology that uses plasmons, which are density waves of electrons created when light hits metal surfaces under certain conditions. Plasmonics could enable faster data transmission over very small wires by combining the best aspects of photonics and electronics. Researchers hope plasmonics can overcome limitations of conventional communication systems and allow for information transfer with greater control at the nanoscale. Potential applications of plasmonics include solar cells, LEDs, invisibility cloaks, cancer treatment, and quantum dot devices for fast computing. However, challenges remain in developing active plasmonic components that can operate at ultra-high bandwidths and low power.

2. Introduction
• Currently communication systems are based on either
electronics or photonics .
• However , for transporting huge amounts of data at a high
speed along with miniaturisation both these technologies are
facing limitations.
• So researchers are pioneering a new technology called
“PLASMONICS”.

3. What is Plasmonics?
• Plasmonics is the study of the interaction of light and metal
under precise circumstances.
• Plasmonics is thought to embody the strongest points of both
optical and electronic data transfer , allowing the fast
transmission of information over very small wires.
• The term „PLASMONICS‟ is derived from Plasmons.

4. PLASMONS
• Plasmons are density waves of electrons , created when light
hits the surface of metal under precise circumstances.
• These density waves are generated at optical frequencies , and
are very small and rapid.
• They can theoretically encode a lot of information , more than
what‟s possible for conventional electronics.
• Plasmons are the Nanostructured metals.

5. Need for Plasmonics
• Optical fibers now span the entire globe,guiding light signals
that convey voluminous streams of voice command vast
amount of data.
• Photonic devices
• Electronic circuits
• Photons & Electronics
• Mismatched capacities and sizes

6. • Researchers are can cobble them together ,but a single
technology that has the capacity of photonics and smallest of
electronics with the best bridge of all Researchers are
pioneering such technology called “ PLASMONICS”.
PLASMONICS breaks the fact :
The fact that light interacts with
nanostructures overcome the belief held for more than a
century that light waves couldn‟t interact with anything
smaller than their own wavelengths.

7. Communication with plasmonics
• Huge control over EM waves at Nano-scale.
• Surface Plasmons generated at the metal dielectric interface
cloud allow plasmons to travel along nano-scale wires.
• In order to fabricate effective plasmonic devices nanostructure
materials must be used.

8. Applications
• Graphene
• Plasmonic solar cells
• Plasmonic LED
• Plasmonsters - A faster chip Graphene structure
• Invisibility cloak - Let‟s fun with mr.india
• Plasmonic Therapy – Cure for cancer
• Quantum dot Plasmonics
• Plasmon printing.

10. Quantum dot plasmonics
• These are the semiconductor nano crystals .
• It couples strongly both photonics and electronic property.
• These are used for making superfast computers that can
transfer data up to 10Gbps .
• Used in optical applications such as imaging

11. Future directions
• To develop new optical components and systems that are of
same size as today smallest integrated chips.
• Plasmon sources , detectors , switches and wires as well as
splitters can be developed.
• Molecular switches
• All frequencies of the visible light must be covered

12. Challenges remaining
• The dream of making all-Plasmonic devices requires further
research .
• In order to realise advanced active circuits , there is a need for
active modulator and components operating at Ultra-high
bandwidth and low power utilisation.

13. Conclusion
• Plasmonics will drive us to a work of high speed
communication network , where we can convey voluminous
stream of voice and vast amount of data . Plasmonics is the
great boon of nano technology .
