Abstract
A driver configuration for driving a Mach-Zehnder modulator (MZM) includes a first driver supplied by a first voltage and a second voltage and configured to provide a first two complimentary outputs respectively to a first N-electrode of a first branch of the MZM and a second N-electrode of a second branch of the MZM. Additionally, the driver configuration includes a second driver supplied by a third voltage and a fourth voltage and configured to provide a second two complimentary outputs respectively to a first P-electrode of the first branch and a second P-electrode of the second branch. The driver configuration sets a difference between the third voltage and the fourth voltage equal to a difference between the first voltage and the second voltage to provide a same peak-to-peak differential swing for modulating light wave through each transmission line and output a modulated light with twice of the peak-to-peak differential swing.
