Waveguiding without a waveguide: Local-mode exciton polaritons in multiple quantum wells
نویسنده
چکیده
Exciton polaritons are considered in infinite multiple quantum wells which are periodic except that one well ~impurity! has a different well width from the others ~host!. Under certain circumstances it is possible to have a long-lived exciton-polariton mode localized about the impurity. From the viewpoint of the electromagnetic field, this corresponds to waveguide modes in the vicinity of an exciton resonance in such structures. © 1995 American Institute of Physics.

Light-trapping for room temperature Bose-Einstein condensation in InGaAs quantum wells.
We demonstrate the possibility of room-temperature, thermal equilibrium Bose-Einstein condensation (BEC) of exciton-polaritons in a multiple quantum well (QW) system composed of InGaAs quantum wells surrounded by InP barriers, allowing for the emission of light near telecommunication wavelengths. The QWs are embedded in a cavity consisting of double slanted pore (SP2) photonic crystals composed...
متن کاملExcitonic Radiative Dynamics in Multiple Quantum Wells
The fundamental intrinsic radiative process associated with excitons in semiconductor multiple quantum wells is discussed within the context of exciton polaritons. Multiple quantum wells in which each well is randomly displaced from its ideal periodic position are discussed in order to investigate the effect of disorder on excitonic radiative widths. The coherent transpori of excitons in multip...
متن کاملResonant Rayleigh scattering of exciton-polaritons in multiple quantum wells.
A theoretical concept of resonant Rayleigh scattering (RRS) of exciton-polaritons in multiple quantum wells (QWs) is presented. The optical coupling between excitons in different QWs can strongly affect the RRS dynamics, giving rise to characteristic temporal oscillations on a picosecond scale. Bragg and anti-Bragg arranged QW structures with the same excitonic parameters are predicted to have ...
