Abstract

Disclosed herein are architectures for low power, low voltage traveling wave Mach-Zehnder optical modulators. By combining single-ended series push-pull modulator configurations with differential dual-drive modulator configurations, the advantages of each type may be utilized. In particular, the halved capacitance of single-ended series push-pull modulators may reduce microwave losses, thereby improving bandwidth performance within modulator configurations. Moreover, reduced required drive voltage of dual-drive modulators coupled with increased impedance may advantageously minimize the power consumption and maximize efficiency in the differential traveling wave series push-pull Mach-Zehnder modulator configurations disclosed herein.
