Electron-related nonlinearities in GaAs-Ga1-xAlxAs double quantum wells under the effects of intense laser field and applied electric field
(ELSEVIER SCIENCE BV, 2013)
The combined effects of intense laser radiation and applied electric fields on the intersubband-related linear and nonlinear optical properties in GaAs-based quantum wells are discussed. It is shown that for asymmetric ...
The effect of the intense laser field on the intersubband transitions in Ga1-xInxNyAs1-y/GaAs single quantum well
