Abstract :
The modulation characteristics of a coupled-cavity AlGaAs injection laser have been investigated in the frequency range 0.2 to 1.0 GHz. The laser operates in a single longitudinal mode for almost all injection currents and modulation indices above laser threshold. The phase and amplitude of the current-to-frequency-modulation transfer function of the laser have been measured.
