Abstract
Electrical pulses from 450 fs to 3 ps are generated using coplanar strip lines and coplanar waveguides on SI GaAs substrate. We use two optical pump beams to generate two steplike electrical transients with opposite sign and then superimpose the signals resulting in rectangular shaped pulses. By varying the delay between the two pump beams the pulse width can be adjusted.Keywords
