Abstract
We discuss selection rules and intensities of photocurrent of a two-dimensional electron gas in a strong magnetic field via absorptions of orbital angular momentum carried by obliquely irradiated optical vortex beams. By angular deflection, optical vortex beams on the two-dimensional electron gas interface can be seen as a superposition of the various orbital angular momentum states. As a result, it is demonstrated that it is yielded that the angular momentum selection rules and induced currents are modified from the case of vertical incidence.
