Abstract

Joint time-frequency ultrafast measurements using frequency-resolved optical gating (FROG) have been used to provide a fundamental understanding of: 1) ultrashort pulse propagation in semiconductor optical amplifiers; 2) themode-locking dynamics in external cavity semiconductor diode lasers; and 3) correlated multiple-wavelength generation from mode-locked semiconductor lasers, The pulse shaping and chirping effects measured by FROG are shown to be attributed to intracavity gain and saturable absorbing dynamics, as well as group velocity dispersion. In addition, the intracavity gain dynamicsshow a regime of transient unsaturated gain, which can be exploited to allow phase-correlated multiple-wavelength mode-locked operation from a single-stripe external-cavity semiconductor diode laser. In this case, FROG techniques are used to understand the underlying mechanisms involved in the phase correlation process.
