A long cavity fiber-integrated semiconductor ring laser is demonstrated at
10 GHz. The temporal and spectral characteristics of a harmonically mode-lo
cked laser pulse were described in detail. The laser pulse of 18 ps was com
pressed to a transform-limited pulse duration of 6.8 ps using an opposite d
ispersion chirp compensator in an anomalous dispersion regime. (C) 2000 Els
