A system for probing a DUT is provided, the system comprising a tunable or CW laser source, a modulator for modulating the output of the laser source, a beam optics designed to point a probing beam at a designated location on the DUT, optical detector for detecting the reflected beam, and collection and signal processing electronics.

A system for probing a DUT is disclosed, the system having a pulsed laser source, a CW laser source, beam optics designed to point a reference beam and a probing beam at the same location on the DUT, optical detectors for detecting the reflected reference and probing beams, and a collection electronics. The beam optics is a common-path polarization differential probing (PDP) optics. The common-path PDP optics divides the incident laser beam into two beams of orthogonal polarization—one beam simulating a reference beam while the other simulating a probing beam. Both reference and probing beams are pointed to the same location on the DUT. Due to the intrinsic asymmetry of a CMOS transistor, the interaction of the reference and probing beams with the DUT result in different phase modulation in each beam. This difference can be investigated to study the response of the DUT to the stimulus signal.
