Abstract :
The authors present a calibration method for internal electro-optic sampling of III-V integrated circuits which allows absolute voltage measurements within accuracy of a few percent. Experimental tests are performed on a 50 Ω coplanar GaAs line at multigigahertz frequencies. A 1.55 μm gain-switched laser diode is used as the optical source. Results of potential mapping agree very well with numerical simulations from a finite element model. A value of 3.7 kV (±15%) is estimated for the GaAs half-wave voltage Vπ at the operating frequencies
