dc.description.abstract | We present in this paper the quantum treatment of self-organization phenomena of excitons and biexcitons in the geometry of a ring cavity. Applying the adiabatic elimination method of the exciton and biexciton variables, the Fokker-Planck equation for the transmitted field was obtained. The spectrum of transmission and second order correlation function were calculated. Thus, the spectrum of transmission describes a hysteresis cycle character, where a narrow spectral line in the end of cycle can be observed. The phenomena of optical bistability and switchings of excitons and biexcitons are investigated theoretically. | en_US |
dc.description.abstract | În această lucrare este prezentat un model cuantic de studiu al fenomenelor de auto-organizare a sistemului de excitoni și biexcitoni în cavităţi inelare. Aplicând metoda de eliminare adiabatică a excitonilor și biexcitonilor, s-a obţinut ecuaţia Fokker-Planck pentru câmpul transmis. S-a calculate spectrul de transmisie și funcţia de corelaţie de ordinul doi. După cum a fost observat, spectrul de transmisie descrie comportament de histerezis, cu apariţia unei linii spectrale înguste. Sunt cercetate teoretic fenomenele de bistabilitate optică și comutări ale sistemului de excitoni și biexcitoni. | ro |
