摘要

We propose an adaptive distributed-bias driving method for silicon travelling-wave Mach-Zehnder modulators and achieved ~25% modulation efficiency enhancement at both 10 and 25 Gb/s with <;3.5 V _pp , without optimizing horizontal PN-diodes. This method also suggests a new modulator scheme allowing efficiency improvement and design flexibilities.
