Femtosecond Time Domain Measurements of Group Velocity Dispersion in Diode Lasersat 1.5 Microns

摘要

We have measured the group velocity dispersion of bulk V-groove semiconductorlasers and multiple quantum well lasers operating at a wavelength near 1.5 Jim. Our data yield in the range from -0.63 to -0.95 um-1 and indicate material dispersion is the dominant factor in our diodes. Cross-correlation traces or transmitted femtosecond pulses confirm the measured values of dispersion.
