Inverse design in photonics by topology optimization: tutorial
Rasmus E. Christiansen, Ole Sigmund
Topology optimization methods for inverse design of nano-photonic systems have recently become extremely popular and are presented in various forms and under various names. Approac…
Inverse Design of Nanoparticles for Enhanced Raman Scattering
Rasmus E. Christiansen, Jérôme Michon, Mohammed Benzaouia +2
We show that topology optimization (TO) of metallic resonators can lead to improvement in surface-enhanced Raman scattering (SERS) efficiency compared to traditio…
Maximizing the quality factor to mode volume ratio for ultra-small photonic crystal cavities
Fengwen Wang, Rasmus Ellebæk Christiansen, Yi Yu +2
Small manufacturing-tolerant photonic crystal cavities are systematically designed using topology optimization to enhance the ratio between quality factor and mode volume, Q/V. For…
