Modeling and simulation play increasingly more important roles in the development and commercialization of optical devices and integrated circuits. The current trend in photonic technologies is to push the level of integration and to utilize materials and structures of increasing complexity. On the other hand, the superb characteristics of free-space and fiber-optics continue to hold strong position to serve a wide range of applications. All these constitute significant challenges for the computer-aided modeling, simulation, and design of such optical devices and systems.

520 $a Modeling and simulation play increasingly more important roles in the development and commercialization of optical devices and integrated circuits. The current trend in photonic technologies is to push the level of integration and to utilize materials and structures of increasing complexity. On the other hand, the superb characteristics of free-space and fiber-optics continue to hold strong position to serve a wide range of applications. All these constitute significant challenges for the computer-aided modeling, simulation, and design of such optical devices and systems.
520 $a The research work in this thesis deals with investigation and development of advanced finite-difference time-domain (FDTD) methods with focus on emerging optical devices and integrated circuits with complex material and/or structural properties. On the material aspects, we consider in a systematic fashion the dispersive and anisotropic characteristics of different materials (i.e., insulators, semiconductors, and conductors) in a broad wavelength range. The Lorentz model is examined and adapted as a general model for treating the material dispersion in the context of FDTD solutions. A dispersive FDTD method based on the multi-term Lorentz dispersive model is developed and employed for the modeling and design of the optical devices. In the FDTD scheme, the perfectly matched layer (PML) boundary condition is extended to the dispersive medium with arbitrary high order Lorentz terms. Finally, a parameter extraction scheme that links the Lorentz model to the experimental results is established.
520 $a Further, the dispersive FDTD method is then applied to modeling and simulation of magneto-optical (MO) disk system, in combination of the vector diffraction theory. While the former is used for analysis of the interaction of the focused optical field interacting with the conducting materials on the surface of disk, the latter is to simulate the beam propagation from the objective lens to the disk surface. The combination of these two methods therefore allows for simulation of the entire MO disk systems so that the system performance such as tracking-error signal and readout signal can be predicted against key design parameters of the disks (e.g., groove, pit and mark).
