FIG. 1.

Experimental schematic of the multiwavelength spectroscopy system.

FIG. 2.

Measured ASE spectrum at a bias of 260 mA is shown as a broad spectrum together with the narrower pulse spectrum. Also shown are the spectral locations of three CW probe signals at 1530 nm, 1550 nm, and 1570 nm. The inset shows an electron micrograph of the QDashes revealing their quantum wire like nature.

FIG. 3.

Delay time dependent probe transmission at 1530 nm, 1550 nm, and 1570 nm. The pulse cross-correlation is superimposed for reference.

Image of FIG. 4.
FIG. 4.

Nonlinear nature of the gain media. (a) Normalized transmission level at long delay times as a function of input pump pulse energy. The inset shows pulse energy dependent transmission at 1550 nm for long delay times. (b) Pulse autocorrelation measured at the amplifier output for various input pulse energies.
