SIMPLE TECHNIQUES FOR THE GENERATION OF ULTRASHORT, SYNCHRONIZED ELECTRICAL PULSES

Two simple devices based on Auston switches are described for optoelec tronic pulse generation. The first technique uses a partially illumina ted gap and produces variable pulse durations less than or equal to 21 ps and amplitudes in the 5 V range. The second device benefits from t he carrier lifetime shortening of proton-implanted GaAs yielding pulse s of 12 ps and 500 mV. (C) 1995 American Institute of Physics.
