We analyze and measure the electrical properties of a hybrid coplanar/ microstrip traveling‐wave optical modulator containing an InGaAs/InAlAs quantum‐well electron transfer structure. S‐parameter measurements to 20 GHz reveal the microwave refractive index and microwave loss as a function of waveguide geometry. These experiments allow us to project electro‐optical modulation bandwidths in excess of 40 GHz. © 1995 John Wiley & Sons, Inc.
