FIG. 3.

One module band diagram for TWIGS254. Layers are labeled by their thicknesses in nm. The 3.4 nm barrier is delta-doped in the middle to .

FIG. 4.

Experimental data for TWIGS254 clad in Ta/Au waveguides with dry-etched defined mesas. (a) L-I versus temperature. (b) I-V at 8 K. The dotted lines mark the lasing dynamic range in current (compare (a)). The arrow marks the parasitic shoulder attributed to alignment between the injector and lower laser levels.
