Abstract

We present a simple homodyne phase measurement instrument to evaluate a light‐induced birefringence change in an Mg‐doped congruent lithium niobate crystal by using an integrated lithium niobate Zn‐indiffused phase modulator (ZIPM) for optical signal modulations.The results successfully demonstrate that the focused beam and modulated phase of the ZIPM can provide a simple pump‐probe method for measuring the evolutions of light‐induced birefringence changes. The detection of birefringence change at the level of 10^−7^ is lower than the conventional Senarmont compensation method. © 2010 Wiley Periodicals, Inc.
