我们提出了一种新颖的薄片X切割LiNbO/sub3/光调制器结构，它可以通过精密抛光和研磨来获得更薄的LiNbO/sub3/衬底，除了速度匹配和阻抗匹配外，还可以获得更低的驱动电压。结果表明，该调制器的驱动电压V/SPL pi/为2V，在40 Gb/S工作时为零啁啾，具有很高的抑制直流漂移的潜力和长期的可靠性。
We present a novel thin-sheet X-cut LiNbO/sub 3/ optical modulator structure which can be fabricated by precise polishing and lapping to obtain a thinner LiNbO/sub 3/ substrate for a lower driving voltage in addition to velocity matching and impedance matching. We demonstrated that the fabricated modulator had a driving voltage V/spl pi/ of 2 V and zero chirp for 40-Gb/s operation and had a high potential for suppressed dc drift, and long-term reliability.
