Abstract

We proposed an optical modulator of reflective type to compose the electric field sensor, and theoretically analyzed the performance and characteristics. For the high sensitivity of the sensor, a method to improve the modulation index of the modulator was presented. The electric field sensor using Ti:LiNbO$_{3}$ waveguide was fabricated and qualitatively investigated the characteristics by measuring the low frequency electric field. Even though the sensor showed relatively low modulation index, the electric filed strength of 10$^{-2}$V/m was measured. The experimental results revealed the utilities of this type electric field sensor.
