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 cathode of a first arm optical phase shifter of a TWE MZM. The second differential output is DC coupled to a cathode of a second arm optical phase shifter of the TWE MZM. The first capacitor AC couples the second differential output to an anode of the first arm optical phase shifter. The second capacitor AC couples the first differential output to an anode of the second arm optical phase shifter. The first and second terminations are coupled to the cathode and the anode of, respectively, the first or second arm optical phase shifter.
