In traveling-wave Mach-Zehnder Modulators (TW-MZMs), the RF electrode acts as a transmission line as opposed to a concentrated capacitor, as is the case in lumped modulators. Foundry process variations can intr
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 ...
We report the design, fabrication, and testing of a traveling-wave Mach-Zehnder modulator on a GaAs substrate. Operating at 870-nm wavelength, we obtained an extremely low driving voltage of 0.45 V and a high measurement-instrument-limited small-signal modulation bandwidth of 18 GHz, projected ...
SEGMENTED TRAVELING WAVE OPTICAL MODULATORS AND RELATED METHODS A segmented traveling wave Mach Zehnder optical modulator is described.
