A Review paper by Yoseph Shin titled “Anisotropic Metamaterials for Scalable Photonic Integrated Circuits: A Review on Subwavelength Gratings for High-Density Integration” has been published in Nanophotonics journal.
Please check out the areas of expertise we’ve developed over the past few years – SWGs for high-density PIC integration! Link: https://www.degruyter.com/document/doi/10.1515/nanoph-2024-0627
Sangsik’s paper on “Exceptional points in lossy media lead to deep polynomial wave penetration with spatially uniform power loss” was published in Nature Nanotechnology!
This project collaborates with NIST scientists, where Sangsik initiated the idea while he was a postdoc at NIST. It took a long time, but finally out there for disclosure. Check out the original journal (view-only version) and NIST News about it!
