We have investigated the infrared transmission of a
two-dimensional electron gas (2DEG) confined in a
single quantum
well in order to study the electron optical phonon interaction in
a two-phonon mode system. Infrared transmission experiments have
been performed in both the perpendicular Faraday (PF) and tilted
Faraday (TF) configurations for which the growth axis of the
sample is tilted with respect to the incident light propagation
direction and to the magnetic-field direction. The experimental
results lead to question the validity of the concept of polaron
mass in a real material.
