We report on the observation of the electronic Landau level splitting in Bragg confining structures (BCS) under an applied magnetic field at T = 2 K. The BCS consists of finite GaAs/Al0.32Ga0.68As superlattice (SL) sections that clad Al0.32Ga0.68As spacer layers. The SL sections act as Bragg reflectors that give rise to confined electron and hole states in the spacer layers (eB, hhB and lhB). The Landau levels are observed in the photoluminescence excitation spectra in the Faraday configuration. The electron and hole cyclotron frequencies correspond to a two-dimensional motion in the Bragg confining barrier. We use the magnetic field dependence in order to determine the eB-hhB and eB-lhB band gaps and from these we find the Bragg confined exciton binding energy.
