dc.description.abstractTraveling wave directional coupler-type electro-optic modulators based on GaAs Schottky contact microstrip lines are modeled and analyzed. The microwave propagation including losses in the structure is described by a simple quasi-TEM model. The lightwave propagation is calculated numerically including multiple layer effects as well as Schottky metal cladding effects. A simple figure of merit is used to compare and optimize structures. The results show that the effects of microwave attenuation dominate those of velocity and impedance mismatching at more than 1 GHz and that the device performance is strongly dependent on the operating voltage.-
