Abstract
We demonstrate a low half-wave voltage (0.7 V), high-bandwidth modulator in thin-film lithium niobate operating at near-infrared wavelengths (850 nm) and show the ability to transmit 60 GBd signals with direct electrical driving (400 mVpp). This paves the way for high-bandwidth, low-power, and compact optical engines for short-range optical communication.
