Image of FIG. 1.
FIG. 1.

(a) Streak image of the PL emission for the active region of the investigated structure at 10 K . (b) Horizontal profiles of the streak image taken shortly after pulse arrival and at a longer time scale together with their spectral components [(c)–(e)]. (f) The peak position of the high energy (circles) and low energy (squares) spectral components together with their intensities indicated by the symbol size.

FIG. 2.

Dependence of the QW (circles) and LS (squares) emission peaks vs . The size of the points represents peak intensity.

Image of FIG. 3.
FIG. 3.

Temperature dependence of the CW PL peak energy position for the active region of investigated structure (circles). The solid line represents a theoretical curve according to the Varshni equation. The inset shows the FWHM parameter vs temperature.

Image of FIG. 4.
FIG. 4.

The TRPL traces taken from the streak image in Fig. 1. The high energy PL trace (circles) is mostly due to the QW emission, whereas the low energy PL trace (squares) is due to the LS emission.
