Abstract: In this talk, two challenging problems of photonic device modeling will be addressed: 1) multiscale modeling and 2) optimization. When it comes to model an optically large system with subwavelength features, a multiscale simulation scheme is required. In other words, your simulation tool should be able to handle both the interaction of light at sub-wavelength scale and propagation of light in large distances. In the first part of this talk, a multiscale simulation (a special type of Multiphysics simulation) scheme which combines full wave and ray optics approaches will be demonstrated. On the other hand, for most of the photonic component design processes, the goal is to match a predefined component functionality, for most of the cases, a predefined spectral response. In the second part of this talk, an optimization scheme to design photonic components will be demonstrated.
