Polariton Local States in Periodic Bragg Multiple Quantum Well Structures
Abstract
Defect polariton states in Bragg multiple-quantum-well structures are studied along with defect induced changes in transmission and reflection spectra. Analytical results for eigen frequencies of the local states and for respective transmission coefficients are obtained. It is shown that the local polaritons result in resonance tunneling of light through the stop band of MQW structure but unlike other types of local states the transmission resonance frequencies are always shifted with respect to eigen frequencies of the local modes. Exciton homogeneous broadening is taken into account phenomenologically and recommendations regarding the experimental observation of the predicted effects are given.
