Bidirectional Vectorial Holography Using Bi-Layer Metasurfaces and Its Application to Optical Encryption
Hyeonhee Kim, Joonkyo Jung, Jonghwa Shin
The study of optical systems with asymmetric responses has grown significantly due to their broad application potential in various fields. In particular, Janus metasurfaces are not…
Comment on "Amplified emission and lasing in photonic time crystals"
Jagang Park, Hee Chul Park, Kyungmin Lee +5
Lyubarov et al. (Research Articles, 22 July 2022, p. 425) claim that the spontaneous emission rate of an atom vanishes at the momentum gap edges of photonic Floquet media. We show…
Daylong sub-ambient radiative cooling with full color exterior
Suwan Jeon, Soomin Son, Seokhwan Min +3
Terrestrial radiative cooling is an intriguing way to mitigate the accelerating cooling demands in the residential and commercial sectors by offering zero-energy cooling. However,…
Spontaneous generation and active manipulation of real-space optical vortex
Dongha Kim, Arthur Baucour, Yun-Seok Choi +2
Optical vortices host the orbital nature of photons, which offers an extra degree of freedom in photonic applications. Unlike vortices in other physical entities, optical vortices…
Universal metasurfaces for complete linear control of coherent light transmission
Taeyong Chang, Joonkyo Jung, Sang-Hyeon Nam +6
Recent advances in metasurfaces and optical nanostructures have enabled complex control of incident light with optically thin devices. However, it has thus far been unclear whether…
Ideal spectral emissivity design for extreme radiative cooling
Suwan Jeon, Jonghwa Shin
Radiative coolers that can passively cool objects by radiating heat into the outer space have recently received much attention. However, the ultimate limits of their performance as…
