Step-like multi-photon absorption in two-dimensional semiconductors with Rashba spin-orbit coupling in terahertz regime

Conference Paper


Abstract


  • We show that due to Rashba spin-orbit coupling two-dimensional semiconductors can exhibit strong nonlinear optical response in the terahertz frequency regime. The spin-split of the parabolic energy band in semiconductors allows multiple-photon process to occur via inter-subband transitions. The steplike edges in the optical process correspond to the cut-off effect produced by the multiple-photon process.
