Modern photonics research and technology is increasingly reliant on efficient numerical methods which can accurately model the optical properties either of advanced components such as high-index waveguides, microstructured fibres, microresonators or metamaterials such as photonic crystals, etc. Also, there is an increasing interest in using nonlinear effects for all-optical signal processing so a basic knowledge of numerical modeling tools for both linear and nonlinear optical phenomena is important for anyone doing photonics research or development. This course aims to give its participants a basic understanding of some common numerical methods, emphasizing both the underlying mathematics, algorithmic issues encountered in their implementation, and their performance in solving some important photonics problems. Methods to be discussed are:
Frequency-domain methods: The finite-difference method for straight waveguides.
Time-domain methods: The finite-difference time-domain method for modeling advanced photonics components. Nonlinear propagation: The split-step Fourier method.
