145966 - An Efficient Topology Optimization Approach for Integrated Photonics Interconnects 

Integrated photonics structure design requires iterative optimization processes to ensure fabrication viability, high efficiency, and structural integrity. Topology optimization - an inverse design tool that can solve large scale design problems with a massive number of degrees of freedom – can be used to optimize electromagnetic structures. In this study, we use a density-based topology optimization method to minimize the field overlap integral. Our method uses a novel approaches to update the binarization parameters which leads to black and white final design to ensure physically realizable material distribution from intermediate densities and obtain efficient designs simultaneously, ensuring fabrication. Multiple examples are presented to demonstrate the viability of the proposed method.
