Abstract :
An electrooptic phase modulator was designed and fabricated, using the quadratic electrooptic effect in PLZT (lead lanthanum zirconate titanate) ceramic of composition 10/65/35. The modulator can be operated at either the fundamental or double frequency of the AC signal driver. The modulator proved effective as a phase modulation device in a phase-detection-based measurement of a small birefringence shift in thin-film materials
