Analysis and modeling of lossy planar optical waveguides and application to silicon-based structures

Creator:

Remley, Catherine A.

Abstract:

This work is concerned with the modeling and analysis of lossy planar dielectric optical waveguides. Loss mechanisms which affect propagation characteristics are reviewed, and various representations of the propagation constant in the lossy case are defined. Waveguide structures which are susceptable to absorption and/or to leakage loss, in particular silicon-based...

Time domain modeling of electromagnetic radiation with application to ultrafast electronic and wireless communication

Creator:

Remley, Catherine A.

Abstract:

A versatile computational technique for improved time domain modeling of electromagnetic radiative systems is demonstrated. Two computational methods are combined: the finite-difference time domain (FDTD) method, a full-wave electromagnetic field solver, and the Kirchhoff surface integral formulation, a spatial transformation technique. The combined FDTD/Kirchhoff technique is shown to increase accuracy...
