COMPREHENSIVE MoL ANALYSIS OF A CLASS OF SEMICONDUCTOR-BASED TRANSMISSION LINES SUITABLE FOR MICROWAVE AND OPTOELECTRONIC APPLICATION.

A comprehensive analysis procedure is presented to investigate mode propagation in a class of semiconductor- based transmission lines suitable for application in microwave or opto-electronic circuits. The method of lines (MoL) has been used to investigate single or multiconductor planar transmission line structures printed on a combination of insulating and semiconducting substrate. Homogeneous as well as inhomogeneous doping areas in the semiconductor are included in the theoretical formulation. Numerical results are presented for 111-V semiconductor travelling wave electro-optic modulators in double-rib, multi-layer strip waveguide configuration, rnicroslab™ transmission lines with partial and full strip cover and slow-wave MIS microstrip/ coplanar transmission lines on thick and thin film semiconductor substrate with gradually inhomogeneous doping layer.
