Bandstructure effects and near-resonant enhancement of the third-order susceptibility in GaAs-AlAs superlattices
We present the results of a full-scale calculation of the third-order susceptibility ( Chi super(3)), for GaAs-AlAs superlattices with a period of 10 lattice constants, illustrating its frequency dependence, and the importance of a full-scale calculation in order to achieve an accurate assessment of...

| Zusammenfassung: | We present the results of a full-scale calculation of the third-order susceptibility ( Chi super(3)), for GaAs-AlAs superlattices with a period of 10 lattice constants, illustrating its frequency dependence, and the importance of a full-scale calculation in order to achieve an accurate assessment of Chi super(3). We also show how bandstructure effects, such as valley-mixing, can affect this enhancement. |
