Uncertainty of the NIST Electrooptic Sampling System



Dylan F. Williams, Paul D. Hale, Tracy S. Clement


We present an uncertainty analysis of measurements performed with NIST's electrooptic sampling system. The system measures the voltage waveform injected by a photodetector on a coplanar waveguide fabricated on an electrooptic LiTaO3 wafer. The frequency response of the photodetector is determined from the voltage measured launched into the coplanar waveguide with a microwave wafer probe. A series of mismatch corrections account for the effects of the probe and coplanar waveguide.
