Near-unity efficiency optical vortex generation in van der Waals materials
Sujeong Byun, Munseong Bae, Hangsung Cho +4
Optical spin-orbit coupling provides a promising, fabrication-free route for developing ultra-compact optical vortex generators. However, the conversion efficiency has been theoret…
Inverse-Designed Metasurfaces for Compact Optical Skyrmion Generation with High Topological Fidelity
Donghyun Park, Alex Song, Haejun Chung +1
Optical skyrmions are structured vector fields with nontrivial polarization topology and subwavelength-scale features. One common approach to generating optical skyrmions is the su…
Enhancing Volumetric Optical Chirality through 2D-3D Structural Design Evolution
Chia-Te Chang, Xiaoyan Zhou, Dmitrii Gromyko +6
Circular dichroism (CD) sensing plays a pivotal role in probing molecular chirality in biomedical sciences. However, engineering superchiral electromagnetic fields that can reliabl…
