Paper Abstract

A novel hybrid-integrated 3D acceleration geophone, based on Mach-Zehnder interferometer, has been developed. Mach-Zehnder waveguide interferometer based on photoelastic effect of LiNbO3 waveguide was researched and its optimization structure design was accomplished The Mach-Zehnder waveguide interferometer is realized by symmetrical double Y-branching waveguide and three polarizers, which are monolithically integrated on an X-cut, Y-propagating LiNbO3 substrate. The simulation results performed in FD-BPM agrees with the theoretical analysis wel1. The Mach-Zehnder interferometer is fabricated successfully and the lighting test is proceeding to check the quality of the Mach-Zehnder interferometer Experimental results matches well with the theoretical prediction.
