Lithium-Tantalate-on-Fused Silica Mach-Zehnder Modulators

2026

Abstract

We demonstrate the lithium-tantalate-on-fused silica (LT-on-FS) Mach-Zehnder modulator manufactured in 4-inch wafer-scale. The modulator features a 3 dB electro-optic bandwidth of 67 GHz and a modulation efficiency of 1.6 V. We achieve net data rates of 437 Gbit/s with PAM8 signaling.
