FIG. 1.

(a) Spontaneous emission (Fabry–Perot device) and DFB single-mode line of structure S1 at 78 K. The inset shows an expanded view of the laser emission. (b) Luminescence-voltage characteristics of the surface emission and the single-facet emission of structure S1 at 78 K. The inset shows a schematic picture of the devices.

FIG. 2.

Normalized spectra of structure S2 (applied current: 5A) in the temperature range between −50 °C and 70 °C. The temperature tuning is .

Image of FIG. 3.
FIG. 3.

Normalized surface beam intensity distributions in the direction of the laser ridges for structure S1 (laser length 2.55 mm, 78 K) and S2 (laser length 2.3 mm, 300 K).
