The recent development of fabrication techniques and material platforms allows addressing various multi-constrained problems in many areas including on-chip circuitry, imaging, sensing, energy, and quantum information technology. However, these require advanced design development methods, which can go beyond conventional optimization. We will discuss recent and promising advances in the development of photonic components based on topology optimization. One of the main aspects of current work is expanding and streamlining a conventional meta-device design methodology to a global optimization space. Specifically, we will cover our recent efforts on coupling topology optimization techniques with deep generative algorithms for dielectric/plasmonic metastructure design development.
