Picosecond pulse generation from InGaAsP lasers at 1.25 and 1.3 µm by electrical pulse pumping

Picosecond optical pulses are generated from InGaAsP lasers by short electrical pulse pumping, Detection limited pulses with a duration of less than 66 ps are observed. In this paper, we report the characteristics of the light output. Results on the stacking of pulses as close as 220 ps are also presented.
