Abstract : Sideband instabilities in the intensity spectrum of synchronously mode-locked external cavity semiconductor lasers are investigated as a function of the cavity length and frequency detuning. A sideband spectrum with distinct narrow lines is observed in the optical power spectrum for modulation frequencies smaller than the inverse photon round trip time and is attributed to frequency and phase modulation of the modelocked pulse train.
