Summary on Grant Application Form |
|
The proposal requests funds to move the field of polariton physics in strong coupling microcavities into new highly promising directions. Major new opportunities arise as a result of recent advances in microcavity physics we have achieved, and as a result of the novel features of polariton excitations in microcavities. The key features of polaritons include their bosonic character, stimulated scattering, very light mass leading to very high critical temperatures for condensation, ease in reaching quantum degeneracy and direct coupling to external photons. These key properties open up major opportunities for new physics (boson-condensation, state with macroscopic coherence) and new generations of devices including a new form of coherent light source, the polariton laser, very high gain amplifiers and triply resonant frequency converters. The research will be carried out on high quality GaAs structures to investigate new phenomena particularly in coupled cavities, and on high exciton oscillator strength, high exciton binding energy GaN and organic systems. The high oscillator strength, high exciton binding energy systems are likely to enable much new physics as a result of their high stability to screening and ionisation, and importantly will enable observation of the phenomena at substantially higher temperatures up to and including room temperature.The proposal requests funds to move the field of polariton physics in strong coupling microcavities into new highly promising directions.
