Fig. 1. Schematic of the fabricated device geometry.

Fig. 2. (a) Schematic of the setup used to test the obtained bandgap shift and (b) band edge comparison between nonintermixed and intermixed cases for 2 μm wide waveguides.

Fig. 3. Comparison between pulses with FWHM of (a) 1.4 ps and (b) 2.7 ps for a SMLL whose blue-detuned SA is 7% of the total cavity length.

Fig. 4. Color maps show the FWHM of the IAC pulses emitted by the SMLLs with intermixed SAs for absorbers whose length is (left) 1% of the cavity length and (right) 2%.

Fig. 5. Color maps show the areas where the FWHM of the IAC pulses is lower than 2.5 ps for (a) one SMLL with nonintermixed 7% SA and (b) a device with a blue-detuned 7% SA; (c) and (d) show an enlarged section of the maps for currents between 250 and 350 mA.

Fig. 6. Color maps show the TBP of the pulses for (a) one SMLL with nonintermixed 7% SA and (b) a device with a blue-detuned 7% SA, for currents between 250 and 350 mA.
