摘      要：Optical modulators have been and will continue to be essential devices for energy-and cost-efficient optical communication *** silicon and lithium niobate modulators have demonstrated promising performances of low optical loss,low drive voltage,and large modulation ***,DC bias drift is a major drawback of optical modulators using lithium niobate as the active electro-optic ***,we demonstrate high-speed and bias-drift-free Mach–Zehnder modulators based on the heterogeneous silicon and lithium niobate *** devices combine stable thermo-optic DC biases in silicon and ultra-fast electro-optic modulation in lithium niobate,and exhibit a low insertion loss of 1.8 d B,a low half-wave voltage of 3 V,an electro-optic modulation bandwidth of at least 70 GHz,and modulation data rates up to 128 Gb/s.
