FIG. 1.

Measured threshold current density as a function of inverse cavity length. Solid squares indicate devices that start lasing at the ground level and the triangle represents the long device, which starts lasing from the second quantum well level.

FIG. 2.

Measured emission spectra of long device with a wide ridge at a current density of at 288 K under cw operation. The laser line at 0.456 eV corresponds to the ground level transition, whereas the laser line at 0.5 eV corresponds to the excited level transition.

FIG. 3.

Wavelength switching as a function of laser current for a long device, with a wide ridge.

FIG. 4.

Evolution of the measured emission spectra for a long device, with a wide ridge, under cw operation, at 288 K.
