Laser field induced interband absorption in a strained GaAs/GaAlAs double quantum well system

Electron transmission in symmetric and asymmetric double-barrier structures controlled by laser fields

“…The response of the two-dimensional electron density to a laser field in modulation-doped quantum wells has been studied for various field strengths [26]. Theoretical investigations on the effect of laser field intensity on the exciton binding energies have been discussed earlier in double-quantum wells and the results show that the exciton binding energy and the photoionization cross-section depend strongly on the well width and the laser field intensity [27]. The effect of intense laser field on the symmetric and asymmetric Pöschl-Teller potentials has been studied.…”
