Abstract
We report the use of electric field induced second harmonic generation to probe electrical signals in a CMOS chip. The second harmonic of incident 2.3 µm illumination provided by a femtosecond optical parametric oscillator was measured and shown to .depend quadratically on both optical intensity and on the applied DC electric field. By using a near infrared photomultiplier tube it was possible to monitor directly the electrical waveform in the chip on the oscilloscope.
