The use of coplanar waveguide capacitively connected to a ground termination was described to generate short electrical pulses with variable duration. The coplanar waveguide was optically excited by a sliding contact scheme. The electric pulse reflected a electrical pulse with an opposite sign and a variable round trip delay. The generation of short electrical pulses with different peak voltages, widths and signs were also demonstrated on laser-diode-based system, by sliding the pump beam along with the coplanar waveguide.
