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.

 

Biography:  Rüştü Umut Tok joined COMSOL in 2011 as a Senior Applications Engineer. His area of expertise is RF and Wave Optics. He has a B.Sc. degree in Physics, M.Sc. degree in Biomedical Engineering and Ph.D. degree in Mechatronics Engineering. After his Ph.D., he joined UCLA Electrical Engineering Department as a postdoctoral researcher. During his career he involved in several research projects which covers different aspects on electromagnetics and optics such as broadband plasmonic antenna array surfaces, ULF mechanical antennas, ferrite materials and devices, light propagation in tissue.
