in this study, the effect of the electric field on the linear, third order nonlinear and
totalabsorption coefficient and the refractive index changes in the GaAs/GaAlAsquantum well for a
constant tilted magnetic field has been investigated. Furthermore, the effects of the magnetic
field direction (i.e. different tilt angles) and the well parameters as well as the electric field
strength on the opticalproperties have been investigated. The energy levels and wave functions of
the system are calculated by using the effective mass approximation and the compact
density-matrix approach is used for optical transitions.Our results show that theoptical
properties of the system are sensitive to the applied external fields and well dimensions.
