Index Terms—MZI modulator, slope efficiency, spur-free dynamic range, silicon integrated device.Abstract
We investigate the analog performances of a silicon Mach-Zehnder interferometer electro-optical modulator. We characterize the optical responses upon various DC and RF voltage supplies. We also measured the spur-free dynamic range (SFDR) of the modulator using two-tone method, showing maximum SFDR of 40 dBc and 46 dBc respectively for second harmonic distortion and third-order intermodulation distortion.
