Observation of a partially rotating superfluid of exciton-polariton
Daegwang Choi, Min Park, Byoung Yong Oh +6
Rotation of a container holding a viscous fluid forms a vortex which grows with increasing angular velocity. A superfluid, however, is intrinsically different from these normal flu…

Time-reversing a monochromatic subwavelength optical focus by optical phase conjugation of multiply-scattered light
Jongchan Park, Chunghyun Park, KyeoReh Lee +2
Due to its time-reversal nature, optical phase conjugation generates a monochromatic light wave which retraces its propagation paths. Here, we demonstrate the regeneration of a sub…

Scattering optical elements: stand-alone optical elements exploiting multiple light scattering
Jongchan Park, Joong-Yeon Cho, Chunghyun Park +4
Optical design and fabrication techniques are crucial for making optical elements. From conventional lenses to diffractive optical elements, and to recent metasurfaces, various typ…
