Numerical Simulation of the Effects of Electric and Magnetic Fields on the Optical Absorption in a Parabolic Quantum Well

  • Shaffa AlmansourEmail author


In this research, effects of electric and magnetic fields on the electronic transitions and the optical absorption coefficients (OACs) of a AlGaAs/GaAs parabolic quantum well (PQW) have been investigated numerically by solving the one-dimensional Schrödinger equation. The confining potential, the energy levels and their corresponding wavefunctions are determined. Our findings indicate that when we increase the intensity of the magnetic field, the magnitudes of the OACs increase, but a blue shift in their corresponding positions is obtained. In addition, our results show that contrarily to the magnetic field, when we increase the intensity of the applied electric field, the OACs initially shift towards lower energies (red shift) and then towards higher energies (blue shift). The obtained results can help experimenters to design and fabricate some optoelectronic devices based on intersubband transitions using parabolic quantum wells.
