摘要
We 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. Our data yield - lambda-d2n(eff)/d-lambda-2 in the range from -0.63 to -0.95-mu-m-1 and indicate that material dispersion is the dominant factor in our diodes. Cross-correlation traces of transmitted femtosecond pulses confirm the measured values of dispersion.
