Abstract :
A computationally efficient hybrid technique for rigorous analysis of TWPDs and their connections with the embedding microwave circuit is presented. The combination of a 2D drift-diffusion based semiconductor analysis method with a full-wave EM simulator allows the computation of slow wave factor and RF attenuation constant of the TWPD as functions of optical input power. In addition, the interconnection effects in terms of s-parameters between the TWPD and a passive CPW line using airbridge transition are presented.
