Abstract

Subwavelength grating (SWG) structures are extremely versatile optical metamaterials that have become a fundamental design tool for the optimization of photonic devices. The importance of SWG structures arises from their capability to synthesize artificial materials with tailorable optical properties, including refractive index, dispersion, or anisotropy. In this invited talk, our advances in SWG topologies to further expand the design space of silicon photonic devices are discussed. The proposed topologies enable enhanced performance such as bandwidth broadening, polarization independency, or increased feature sizes, paving the way for the next generation of SWG-optimized devices.
