FIG. 1.

(a) EL spectra of a free-running QD laser of structure A at different injection currents. The dashed vertical lines mark the wavelength tuning range achieved by external cavity feedback in Littrow configuration. (b) Lasing spectra of the ECL tuned by rotating the grating.

FIG. 2.

(a) Dependence of the threshold current density of the ECL on the operation wavelength. The dashed horizontal line marks the threshold current density of the free-running QD laser of structure A. (b) L-I curves of the ECL at different operation wavelengths.

Image of FIG. 3.
FIG. 3.

Dependence of the threshold current density of the ECL on the operation wavelength measured in CW mode and pulsed mode, respectively. The inset shows the tuning spectra of the ECL operating in pulsed mode.

Image of FIG. 4.
FIG. 4.

(a) The tuning spectra and (b) the wavelength dependence of threshold current density of the ECL based on the QD laser of structure B. The dashed line in (b) marks the threshold current density of the free-running QD laser.
