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

3. WHAT IS PLASMONICS ?
Plasmonics is the study of interaction of light and metal under precise circumstances.
Plasmonics is thought to embody the strongest points of both optical and electronics 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.
This density waves are generated at optical frequencies, and are very small and rapid.
They can theoritically encode a lot of information, more than what ‘s possible for conventional electrons.
Plasmons are the nano structured metals.

5. NEED OF PLASMONICS
Optical fibres now span the entire global, guiding light signals that convey volumnious streams of voice command vast amount of data
Photonic device
Electronics circuits
Photons and electrons
Mismatched capacities and sizes

6. Researches are can cobble them together, but a single technology that has the capacity of photonics and the smallest of electrons with the best bridge of all researchers are pioneering such technology “PLASMONICS”
PLASMONICS breaks that fact :
The fact that light interacts with nano structures overcome the belief held for more than a century that the light waves could’nt 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.
Inorder to fabricate effective plamons devices nano structure material must be used.

8. APPLICATIONS Graphene Plasmonic solar cell Plasmonic LED
Plasmonsters- A faster chip Graphene structure
Invisibility cloak- let’s fun with mr.India
Plasmonics therapy- cure of cancer
Quantum dot plasmonics
Plasmon printing

10. 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 splitters can be developed.
Molecular switches
All frequencies of the visibile light must be covered.

11. Challenges remaining
The dream of making all – plasmonics devices requires further research.
Inorder to realise advanced active circuits, there is a need for active modulator and components operating at ultra- high bandwidth and low power utilisation.

12. CONCLUSION
Plasmonics will derive 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.
