Abstract

We propose a novel optical instrument to simultaneously measure the phase variations of both orthogonal linear polarizations in a Mach–Zehnder interferometer. An integrated Ti‐indiffused LiNbO~3~ Mach–Zehnder modulator is adopted for phase modulation and the optical homodyne scheme is used to measure the phase variations in the experimental setup. By using the multiplexed capabilities and flexible designs of a LABVIEW‐based platform, the simultaneous measurements with real‐time display of output interferomertic signals, spectrum results, and phase variations for both orthogonal polarizations, have been successfully demonstrated in this study. © 2010 Wiley Periodicals, Inc.
