Inverse-Designed Lithium Niobate Wavelength Demultiplexer via Birefringent Effective Index Approximation
Chihyeon Kim, Minho Choi, Munseong Bae +2
Inverse design of thin-film lithium niobate (TFLN) photonic devices is computationally demanding because optical birefringence and fabrication-induced slanted sidewalls generally r…
Scaling Limits of Multichannel Spectral Routers for Snapshot Imaging
Junseo Han, Seunghyun Lee, Donghyun Kim +1
Inverse-designed spectral routers can enable compact snapshot spectral imaging by directing different wavelengths to designated detector sub-pixels without mechanical scanning or a…
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…
Neural Adjoint Method for Meta-optics: Accelerating Volumetric Inverse Design via Fourier Neural Operators
Chanik Kang, Hyewon Suk, Haejun Chung
Meta-optics promises compact, high-performance imaging and color routing. However, designing high-performance structures is a high-dimensional optimization problem: mapping a desir…
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…
