Abstract
This paper details some direct-delay time measurements on both long- and short-wavelength gain-switched injection lasers using a streak camera. The dependence of time delay on drive current is discussed and new applications of variable-delay optical-pulse generation are proposed. A comprehensive experimental and theoretical investigation of ‘alternate pulsing’ is reported. Finally optical delay measurements have for the first time been carried out on twin-stripe lasers and have determined a new type of optical switch whereby the temporal positions of picosecond pulses are strongly dependent on the relative phase of the electrical drive currents.
