AI-assisted miniaturization of integrated photonic components project


Novel optimization techniques such as nanophotonic inverse design are promising tools to significantly reduce the size of silicon photonic components while maintaining their functionality and performance. Such techniques, on the other hand, generate discrete designs that are characterized by a large number of variables, requiring computation-intensive design process. AI tools can help identify patterns in the high-dimensional design space through the analysis of a dataset of simulated designs. Those patterns can further guide the search for better performing designs and shed light on the behavior of the design space as a whole, revealing its specificities and limitations. Use of various machine learning methods to identify such patterns will be investigated, in particular in the context of designing in-plane devices such as mode and frequency (de)multiplexers. This project is a collaboration between McGill University and the NRC. McGill University will provide experience in the designs of photonic integrated devices and circuits while the NRC will provide expertise in machine learning and photonics.
