Parametric interactions in ion-implanted piezoelectric semiconductor plasmas

Abstract EN

Using a hydrodynamic model of semiconductor plasmas and a coupled mode theory of interacting waves, we present an analytical investigation on parametric interaction in magnetized piezoelectric semiconductor plasma, whose main constituents are the drifting electrons and non-drifting negatively-charged colloidal particles.

The phenomenon of parametric interaction is treated as a three-wave interaction process, involving second-order nonlinearity of the medium.

It is found that the second-order optical susceptibility in ion-implanted semiconductor plasma is modified due to the presence of non-drifting charged colloidal particles.

It is interesting to note that the charged colloids modify the dispersion profile, whereas the gain profile is found to be independent of it.

The present study also suggests that a proper selection of colloid density will lead to anomalous dispersion, which in turns becomes helpful in the generation of squeezed states.
