Atomically-smooth gold crystals help to compress light for nanophotonic applications

Nano-tip is used for the ultra-high-resolution imaging of the image phonon-polaritons in hBN launched by the gold crystal edge. Credit: Jang Research Group Korea Advanced Institute of Science and Technology (KAIST) researchers and their collaborators at home and abroad have successfully demonstrated a new platform for guiding the compressed light waves in very thin van … Read more
