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