Abstract

We propose an x -cut LiNbO 3 optical modulator using gap-embedded patch-antennas for wireless-over-fiber systems. The proposed device is composed of an array of narrow-gap-embedded patch-antennas and an optical waveguide located at the center of the gap without a buffer layer. The modulation efficiency of the proposed x -cut LiNbO 3 optical modulators was enhanced by 6 dB compared to the z -cut LiTaO 3-based devices.
