Two color plasmon excitation in an electron-hole bilayer structure controlled by the spin-orbit interaction

Yang, C. H.; Wright, A.; Gao, F.; Zhang, C.; Zeng, Z.; Xu, W.


The dispersion and intensity of coupled plasma excitation in an electron-hole bilayer with Rashba spin-orbit coupling is calculated. We propose to use the spin-orbit coupling in individual layers to tune the intensity of two plasmons. The mechanism can be used to develop a two color terahertz source with tunable intensities.
