Abstract
A differential TWE MZM includes a differential driver, first and second capacitors, and first and second terminations. The differential driver includes a first differential output and a second differential output that collectively form a differential pair. The first differential output is DC coupled to a first arm optical phase shifter of a TWE MZM. The second differential output is DC coupled to a second arm optical phase shifter of the TWE MZM. The first capacitor AC couples the second differential output to the first arm optical phase shifter. The second capacitor AC couples the first differential output to the second arm optical phase shifter. The first and second terminations are coupled to, respectively, the first or second arm optical phase shifter.
