Image of FIG. 1.
FIG. 1.

Schematic of the AFP EO prober.

FIG. 2.

Complete EO sensing system with an AFP EO prober and a current-tuned laser wavelength closed-loop control system.

Image of FIG. 3.
FIG. 3.

(a) Laser emission spectra for driving currents of 130, 140, and 150 mA. (b) EO signal strength of increasing laser diode driving current. The resonant condition occurs when the driving current was 140 mA.

Image of FIG. 4.
FIG. 4.

Long-term recorded EO signals for the closed-loop control function being turned (a) off and (b) on.

Image of FIG. 5.
FIG. 5.

Sensed waveform of real-time signal on the DUT metal electrodes when the closed-loop control function is (a) on and (b) off. For the result in (a), waveforms for different time interval were overlapped. For the result in (b) the worst-case one was sampled.
