Ultrafast excitation of surface plasmon-polariton through optically induced diffraction grating in GaAs films
We introduce a theoretical model describing femtosecond optically induced processes in a GaAs film. The model is used to study the evolution of permittivity under illumination by two plane waves. Resulting periodic interference pattern induces diffraction grating that enables the excitation of a surface plasmon polariton at the filmsubstrate interface.
