Magnetic field and intense laser radiation effects on the exciton binding energy and interband optical transitions in quantum well wires is calculated using a variational method and in the effective mass approximation. The results obtained show that the exciton binding energies and op interband absorption depend on the sizes of the quantum well wire, intense laser field and magnetic field. The additional confinement of the particles in the quantum well wire offers greater variety of the intense laser field and magnetic field dependence in comparison to three- and two-dimensional materials.

Intersubband Optical Absorption

Within the framework of the effective mass approximation, we have theoretically investigated the linear intersubband optical absorption in a quantum well under external electric and intense laser field. Results obtained show that intersubband optical transition and energy levels in quantum wells can significantly be modified and controlled by the electric field and intense laser field. Generally there is a distinct feature for the case of the intersubband absorption compared with intersubband optical absorption in a quantum well with an applied electric field.

Strained Quantum Well

The band structures and optical gain spectra of GaAsSbN/GaAs compressively strained quantum well (QW) were studied using 10-band k.p approach. We found that a higher Sb and N composition in the quantum well and a thicker well give longer emitting wavelength. The result also shows a suitable combination of Sb and N composition, and QW thickness can achieve 1.3 μm lasing. And, the optical gain spectra with different carrier concentrations will be obtained.
