Microwave coplanar waveguide slow wave structures, suitable for traveling wave electro-optic modulators, were experimentally investigated up to 40 GHz. Velocity matching was achieved by introducing different capacitive elements between the signal and the ground electrodes of otherwise uniform coplanar waveguides (CPWs). Four different types of slow wave structures and uniform coplanar waveguides were designed and fabricated on both semi-insulating GaAs (SI- GaAs) and semi-insulating InP (SI-InP) substrates. The measured s-parameters were used to calculate the characteristic impedance, phase velocity, and microwave loss of these structures. The results are in close agreement with the design values and demonstrate an improved performance on SI-InP substrate.
