Experiments confirm light-squeezing 2-D exciton-polaritons
can exist

7th July 2020by admin0

Measurements of the optical response of 2-D
transition-metal dichalcogenides have now pinpointed real material
systems in which a hypothesized light-squeezing quasiparticle can
form. The 2-D exciton-polariton, which couples light to bound
electron-hole pairs in the form of excitons in an unusual way, can
confine light to dimensions orders of magnitude below the
diffraction limit. Confining light to such a high degree may affect
more than the resolving power of imaging devices and detector
sensitivity. Recent studies of cavity modes have suggested that
highly confined light could also alter the inherent properties of
materials.

    The New Fusion technology is based on a phenomenon called triplet-triplet annihilation (TTA) which is a process in which two triplet excitons annihilate and produce a higher energy singlet exciton.
