FIG. 1.

Spectra of PL under excitation of from the dispersed lamp and PLE of the SQW measured at a temperature of .

Image of FIG. 2.
FIG. 2.

Evolution of PL spectra with varying (a) temperature and (b) excitation power. The spectra in (a) have been normalized at the main peak and offset vertically for clarity. The dotted vertical line is a guide for the eye.

Image of FIG. 3.
FIG. 3.

Dependence of energy at the main PL peak on temperature. The solid curve is the fitting of Varshni equation. The solid circle represents the energy of transition determined by PLE spectrum at .

Image of FIG. 4.
FIG. 4.

Edge-emitted PL spectra of SQW at . The experimental geometry is depicted in the inset. Curves 1 and 3 are measured with polarization perpendicular and in the layer plane. Curve 2 is the nonpolarized PL. Curve 4 is the difference between curves 2 and 3, which represents the PL component polarized perpendicular to the layer plane (transition ).
