Fig. 1. Schematic depiction of the hetero-integrated assembly “laser–heterothyristor switch.”

Fig. 2. Laser pulses obtained for the hetero-integrated assembly “laser–heterothyristor switch” at various operating voltages of the heterothyristor switch. The inset shows the laser pulse width as a function of the operating voltage of the heterothyristor switch.

Fig. 3. Lasing dynamics of the hetero-integrated assembly at an operating voltage of 55 V. (a), (b) Time-resolved near field obtained through linear interpolation of 36 curves measured at 2.7 µm intervals along the x-axis. (c) Measured total output powers of laser pulses, with filled areas indicating contributions from different emitters (LD1 and LD2 shown in Fig. 1). (d) Turn-on time distributions along the apertures of different emitters.

Fig. 4. (a) 1–vertical (black) and 2–lateral (blue) far-field divergences at an operating voltage of 55 V. (b) Lasing spectra at operating voltages of 20, 35, 45, and 55 V.
