Universal zero-crosstalk photonic integration via slab-engineered mode hybridization
Kyungtae Kim, Yoseph Shin, Seungyong Lee +8
Photonic integrated circuits have emerged as a scalable platform for optical computing, communication, and quantum technologies, where high-fidelity optical processing is essential…
Anti-aliased metasurfaces beyond the Nyquist limit
Seokwoo Kim, Joohoon Kim, Kyungtae Kim +2
Sampling is a pivotal element in the design of metasurfaces, enabling a broad spectrum of applications. Despite its flexibility, sampling can result in reduced efficiency and unint…
Mode transition () and hysteresis in microwave-driven low-temperature plasmas
Kyungtae Kim, Woojin Nam, Jimo Lee +2
We discovered a hysteresis in a microwave-driven low-pressure argon plasma during gas pressure change across the transition region between and discharge modes. The hysteres…
Emission of Spin-correlated Matter-wave Jets from Spinor Bose-Einstein Condensates
Kyungtae Kim, Junhyeok Hur, SeungJung Huh +2
We report the observation of matter-wave jet emission in a strongly ferromagnetic spinor Bose-Einstein condensate of Li atoms. Directional atomic beams with $|{F=1,m_F=1}\rangl…
Observation of a strongly ferromagnetic spinor Bose-Einstein condensate
SeungJung Huh, Kyungtae Kim, Kiryang Kwon +1
We report the observation of strongly ferromagnetic spinor Bose-Einstein condensates of Li atoms. The condensates are generated in an optical dipole trap without using ma…
Rapid production of large Li Bose-Einstein condensates using gray molasses
Kyungtae Kim, SeungJung Huh, Kiryang Kwon +1
We demonstrate the production of large Li Bose-Einstein condensates in an optical dipole trap using gray molasses. The sub-Doppler cooling technique reduces the temperatu…
