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.
