Pulsed THz radiation due to phonon-polariton effect in [110] ZnTe crystal
Pulsed THz radiation phonon-polariton effect ZnTe crystal Optics
2012/5/31
Pulsed terahertz (THz) radiation, generated through optical rectification (OR) by exciting [110] ZnTe crystal with ultrafast optical pulses, typically consists of only a few cycles of electromagnetic ...
Polariton waves in nonlinear dielectric medium
dielectric medium phonon-polariton spectrum soliton cnoidal wave all-optical logic gates

The phonon-polariton spectrum in dielectric medium with the third order nonlinearity was theoretically obtained. Dependence of number of polariton spectrum branches on intensity of electromagnetic fie...
Exciton-polariton emission from organic semiconductor optical waveguides
Exciton-polariton emission organic semiconductor optical waveguides
2011/8/17
Abstract: We photo-excite slab polymer waveguides doped with J-aggregating dye molecules and measure the leaky emission from strongly coupled waveguide exciton polariton modes at room temperature. We ...
Long-range surface plasmon polariton excitation at the quantum level
Long-range surface plasmon polariton quantum level
2010/4/9
We provide the quantum mechanical description of the excitation of long-range surface plasmon polaritons (LRSPPs) on thin metallic strips. The excitation process consists of an attenuated-reflection s...

17 May 2007，Physicists in the US say they have witnessed the trademark coherence of a Bose-Einstein condensate in a cooled system of quasiparticles known as "polaritons". Although similar claims have ...
Exciton Polariton Emission from a Resonantly Excited GaAs Microcavity
Exciton Polariton a Resonantly Excited GaAs Microcavity
2010/10/26
Coherent emission efficiency in a 100°A GaAs SQW microcavity was enhanced one order when pumped resonantly at 10 K, compared to the off-resonant excitation. The usual kink observed in the exciton emis...
