Femtosecond time domain measurements of group velocity dispersion in diode lasers at 1.5 mu m

The authors have measured the group velocity dispersion of bulk V-groove semiconductor lasers and multiple quantum well lasers operating at a wavelength near 1.5 mu m. The data yield group velocity dispersions in the range from -0.63 to -0.95 mu m/sup -1/ and indicate that material dispersion is the dominant factor in the diodes. Cross-correlation traces of transmitted femtosecond pulses confirm the measured values of dispersion.>
