High-Speed, Low-Driving-Voltage and Small-Footprint X-Cut Thin LiNbO3 Sheet Optical Modulator with a Folded Mach-Zehnder Waveguide

摘要

We proposed an X-cut thin LiNbO3 sheet modulator with a folded Mach-Zehnder waveguide. A small footprint of 1.78??29mm, a low half-wave voltage of 2.4V@DC, and a 3dBe modulation bandwidth of 14GHz were achieved.
