Abstract
We present a mechanism to excite intersubband transitions at normal incidence in quantum wells with a magnetic field applied parallel to the two-dimensional electron gas. In the Voigt configuration the light polarization perpendicular to the magnetic field induces intersubband transitions whose oscillator strength is proportional to the square of the field. This dependence allows us to determine experimentally the intersubband matrix elements with great accuracy.
