摘要：
A symmetric optical modulator with low driving voltage, wherein polarization of any one of branched waveguides formed on a substrate is inverted, and the two branched waveguides are simultaneously controlled by a center electrode formed on a top portion thereof, thereby ensuring a low voltage driving and embodying a characteristic of there being no signal distortion due to chirp.
