Abstract
Coplanar strips, capacitively loaded with fins and pads and capable of achieving the microwave/optical wave velocity-match condition in GaAs - and InP-based electrooptic modulators, are described, Measurements o n electrodes, fabricated to have dimensions appropriate for use in con ventional, Mach-Zehnder-type modulators in the 5-40 GHz range, show th at these electrode structures can be made to obtain the desired match between the microwave effective index and the effective indexes of AlG aAs and InGaAsP optical waveguides, while having loss coefficients sim ilar to 0.7 Np/cm at 40 GHz.
