Abstract
The issue of parameters measurements of picosecond electric pulses with bandwidth of 110 GHz and above is considered. It is proposed to use the electro-optic sampling system for the measurements. Several configurations of coplanar waveguide used as a probe in the electro-optic sampling system are presented; dimensions of waveguide with GaAs substrate are calculated. Beam energy values are calculated for the electro-optic sampling system where passed probe beam parameters are under investigation. Optical design is discussed briefly. Some optical components parameters are estimated. The issues of the sensitivity of the electro-optic sampling system and laser beam focusing into spot with a diameter of about tens of micrometers are covered.
