FIG. 1.

Schematic of the experimental setup used to acquire single-shot measurements of the BA-VCSEL’s spectrally dispersed near field profiles. The temporal resolution/exposure time is .

FIG. 2.

Sequence of single-shot measurements of the BA-VCSEL’s spectrally dispersed near field profiles at different temporal positions . The current amplitude of the long electrical pulses is .

FIG. 3.

Wavelength shift and relative temperature shift of the BA-VCSEL’s emission. The spectral positions were obtained by determining the positions of the parabola vertices (squares) and parabola maxima (triangles) in the single-shot measurements recorded at different . The BA-VCSEL was operated with the same conditions as in Fig. 2.

FIG. 4.

Evolution of the absolute radial temperature distribution at different . The underlying spectral widths and radial positions were determined using the single-shot measurements recorded at different . Positive and negative values of correspond to the radial direction with respect to the center of the VCSEL aperture , as indicated in Fig. 2. The BA-VCSEL was operated with the same conditions as in Figs. 2 and 3.
