Image of FIG. 1.
FIG. 1.

(Color online) Epitaxial structure of the investigated quantum dashes and AFM picture showing 1 × 1 μm2 of the top layer of a 5-layer stack quantum dash structure fabricated with the same techniques as for the one used for the lasers presented in this paper.

Image of FIG. 2.
FIG. 2.

(Color online) Pictures of the 4-mm and 1-mm lasers fabricated. Output facet is on the left; saturable absorber section is on the right edge. The three consecutive sections from the output facet (or two for the 1-mm laser) were shortened to make them equivalent to one section during the characterization.

FIG. 3.

(Color online) Output power vs input current under uniform injection and as a function of the reverse bias voltage over the saturable absorber (SA) for the 4-mm (a) and 1-mm (b) lasers. The black arrows represent the increase direction of the reverse bias voltage.

FIG. 4.

Optical spectra of the 4-mm and 1-mm lasers for an output power of about 8 mW with absorber section reverse biased.

FIG. 5.

Pulse width vs filter peak wavelength with eye guide for the 4-mm laser.

Image of FIG. 6.
FIG. 6.

RF spectra for the 4-mm laser without chirp compensation and with optimal chirp compensation.

FIG. 7.

Autocorrelation trace of the 4-mm laser output with +10.9 ps/nm dispersion compensation (540 m SMF) and Gaussian fit.

Image of FIG. 8.
FIG. 8.

Autocorrelation trace for the 1-mm laser output with +1.15 ps/nm dispersion compensation (60 m SMF) and Gaussian fit. Inset is the auto/cross-correlation measurement without dispersion compensation.

(Color online) Single sideband (SSB) phase noise measurement of the 4-mm laser with +10.9 ps/nm dispersion compensation.

Image of FIG. 11.
FIG. 11.

(Color online) Jitter measurement of the 4-mm laser with +10.9 ps/nm dispersion compensation.
