Normal Mode Coupling in Optical Lattices of Excitons In Periodic Quantum Well Structures

Aperiodic arrangement of planes of identical two-level atoms in a one-dimensional (1D) optical lattice with a period close to an integer value of half the resonance wavelength represents a fundamental model system. An example of actual physical systems under investigation are cold atoms arranged in periodic light shift potentials. The interaction of such an optical lattice with resonant light drastically changes the absorption and emission properties compared to an isolated resonance due to multiple reflections and interference.
