Topology Optimization of Building Blocks for Photonic Integrated Circuits

Photonic integrated circuits are likely candidates as high speed replacements for the standard electrical integrated circuits of today. However, in order to obtain a satisfactorily performance many design prob- lems that up until now have resulted in too high losses must be resolved. In this work we demonstrate how the method of topology optimization can be used to design a variety of high performance building blocks for the future circuits.
