Abstract
In this work, we have studied the possibility of modulating the time-v arying dipole moment of excitons in an asymmetric double quantum well system through an external applied magnetic field. In this way, a tuna ble terahertz radiation emerging from the coupled quantum wells is obt ained. The magnetic field direction is perpendicular to the double-wel l heterostructure growth axis obtaining a significance field-effect on the device for small B values.
