Paper Abstract

The thermal characteristics of a lithium niobate integrated-optic voltage sensor with variable sensing ranges are described. The sensor consists of a Mach-Zehnder interferometric modulator with an array of buried electrodes on the X-cut lithium niobate substrate. The bias stability and scale factor variation due to temperature change are measured by the harmonic component measurement method. The bias phase remains stable to a total variation of 2° over 10∼50°C and the scale factor increases about 0.1% per 1°C increment.
