Full-wave analysis demonstrates that a picosecond electrical pulse can be generated by a pulse-forming optoelectronic device, composed of a photoconductor and an impedance mismatch structure in a coplanar stripline. An electro-optic sampling system is used to measure the response of the pulse-forming optoelectronic device, fabricated on a semi-insulating GaAs substrate. Electrical pulses with 1.3 ps duration (full width at half maximum) are achieved using the device.

    We apply a pump- and probe-scheme to coplanar stripline circuits to investigate the photocurrent response of GaAs photoswitches in time and space. We find a displacement current pulse, as reported earlier. We interpret a time-delayed second pulse as a transport current. In a time-of-flight...

    We demonstrate that applying optoelectronic feedback to a high-speed, self-pulsing semiconductor laser is an effective and practical means of generating picosecond optical pulses (∼10-20 ps) at a very high repetition rate, between 1 to 5 GHz, which can be electrically tuned. The optical...
