Scalable Integrated Nanophotonics with Subwavelength Gratings

Photonic integrated circuits (PICs) have innovated a wide range of optical applications, including quantum processing, biochemical sensing, and light detection and ranging (LiDAR). As electronics, increasing the chip density is critical for advancing PICs but limited by the wave nature of light. In this project, the Texas Tech team led by Dr. Sangsik Kim will explore the various subwavelength grating (SWG) metamaterials to push the boundaries of photonic integration density. SWGs have engineering capabilities for index contrast and anisotropic nature, and various next-generation SWG schemes will be investigated for reducing optical crosstalk. Diverse SWG photonic components, including in-plane metalens, will also be developed and integrated to hybridize photonic and microfluidic systems. This project also aims to support a rich hands-on experience with PICs, allowing TTU students to explore future photonic technologies.
