Abstract

The change in the interband-absorption properties of a quantum wire due to the optical near field is investigated. Calculation results show that the near field can enhance or reduce the absorption, depending on the geometry of the quantum wire and the incident direction of light.

  18. Several theoretical studies have reported that quantum confinement in two dimensions significantly modifies the valence-band structures (see Refs. 2 and 3 and the references therein). That is, the heavy-hole and the light-hole states are strongly mixed even at the zone center. (Note that zone center is assumed in this paper.) Therefore we have to consider the band-coupling (mixing) effects in QWR structures for the exact quantitative calculation. However, we did not include them for simplicity. Our main claim is that the optical near field can change the field distributions in a QWR, and this change modifies the optical absorption properties of a QWR. The change in optical fields is not dependent on the specific calculation method of electronic states of a QWR. Therefore we can say that although our calculation of electronic states of a QWR neglecting band-mixing effects limits the accuracy of our modeling, it does not change the physics investigated in this paper.

  27. We can adopt simpler models used in the electrodynamics text books to see only a qualitative effect of the optical near field [e.g., the dipole approximation that regards the inhomogeneity as a circular dipole, J. D. Jackson, Classical Electrodynamics, 3rd ed. (Wiley, New York, 1999), Chap. 4]. However, to see the quantitative change of this effect depending on the geometry of the QWR (this is one of the main claims of this paper), we have to use a more rigorous method that can deal with inhomogeneities of arbitrary shape.

  31. The exciton level in the QWR would be much closer to the resonance energy between the ground states of the conduction and heavy-hole bands (ħω00). Then, Eq. (9) reduces to ε(ω)≅εoff+ifexcNexce2/mexc2ωγexc+f00Nhhe2/mhh2ωγ00, and the refractive-index change can be negligible.
