OPTICAL MODULATOR

Abstract: an optical modulator includes two optical waveguide arms, each including a plurality of phase modulators. the phase modulators in each waveguide arm are electrically coupled to a single transmission line or between a pair of single-ended transmission lines to be differentially driven when the transmission line pair is connected to a differential driver. inductors are positioned in each of the transmission lines to increase the overall impedance of the modulator to match an impedance of other electro-optical devices in a circuit. electrical and optical signal velocity matching is provided by waveguide delay lines.
