If another photon is simultaneously traveling through the cloud, it can also spend some time on a rubidium atom, forming a polariton -- a hybrid that is part photon, part atom.
University of Cambridge researchers, led by Professor Jeremy Baumberg from the NanoPhotonics Centre, in collaboration with researchers from Mexico and Greece, have built a switch which utilises a new state of matter called a polariton Bose-Einstein condensate in order to mix electrical and optical signals, while using miniscule amounts of energy.
As the light strikes the sensing area, it excites free electrons, causing them to oscillate and generate a highly confined propagating surface wave, called a surface plasmon polariton.
Polariton An exciton or similar particle coupled to a photon; leading to energy-efficient lasers
0] and the plasmonic-polariton excitations: (i) happens in the frequency range where Re(n) is negative and the inverse Cherenkov emission occurs, and (ii) the value of the metamaterial refraction index (and thus the polariton phase velocity) depends on the particle velocity [[upsilon].
If the propagation constant of the incident light in dielectric medium is matched with that of the SP at metal-dielectric interface the surface plasmon polariton (SPP) mode is generated.
Metaspacers can be designed to support different types of surface plasmon polariton (SPP) modes.
Most of these effects appears due to an excitation of Surface Plasmon Polariton (SPP) resonances.

One characteristic of these plasmons is that they can join with a photon to become a surface plasmon polariton (SPP) which can travel along the surface of the metal until it dissipates its energy in to the metal or through radiation in to the adjoining medium - such as air.
