Abstract: On-chip silicon photonic devices are poised to continue transforming capabilities across multiple sectors, including data center transceivers, optical interconnects, LiDAR, and immunoassays. While most silicon photonic components are based on traditional waveguide-based building blocks, this talk will introduce new opportunities that can be enabled by introducing subwavelength engineered features into optical waveguides and cavities. In particular, we will discuss how to deterministically modify the unit cells of photonic crystal waveguides and cavities with subwavelength engineered features to control the field distribution and peak energy density of optical modes. We will also discuss how these subwavelength engineered structures can enable enhanced performance metrics in on-chip modulators, optical nanotweezers, and optical biosensors. Finally, perspectives on scalable foundry fabrication of subwavelength engineered photonic components will be provided.
