✦ Synopsis

The finite difference in the frequency domain (FD-FD) method is used here to analyze the propagation characteristics of a lossy dielectric waveguide. These characteristics are optically controlled by means of light incidence on a semiconductor layer positioned on the dielectric waueguide. In the formulation the uector waue equation, which describes the waue propagation, is expressed in terms of the transverse components of the magnetic field in a form of a conuentional eigenualue problem, and the spurious modes are eliminated, by implicitly including that the diueigence of the magnetic field is zero.

The FD-TD method was used to model physical chip resistors with the use of the lumped-element concept. Instead of using the con¨entional planar resisti¨e elements approximation, we modeled the substrate on which the resisti¨e element is fabricated as well. Comparing our numerical results with experi
