Purcell enhanced and blinking free single photons from InAs/GaAs quantum dots in deterministically placed circular Bragg gratings
Peter Gschwandtner, Quirin Buchinger, Krishna Chand Maurya +11
The development of efficient, deterministic, and tunable single-photon sources is a cornerstone for the realization of long-distance quantum communication, quantum repeaters, and p…
Single quantum dot selection and tailor-made photonic device integration using nanoscale focus pinspot
Minho Choi, Mireu Lee, Sung-Yul L. Park +6
Among the diverse platforms of quantum light sources, epitaxially grown semiconductor quantum dots (QDs) are one of the most attractive workhorses for realizing various quantum pho…
1D photonic crystal direct bandgap GeSn-on-insulator laser
Hyo-Jun Joo, Youngmin Kim, Daniel Burt +12
GeSn alloys have been regarded as a potential lasing material for a complementary metal-oxide-semiconductor (CMOS)-compatible light source. Despite their remarkable progress, all G…
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…
Direct Transfer of Light's Orbital Angular Momentum onto Non-resonantly Excited Polariton Superfluid
Byoung Yong Oh, Min-Sik Kwon, Su-Hyun Gong +6
Recently, exciton-polaritons in a semiconductor microcavity were found to condense into a coherent ground state much like a Bose-Einstein condensate and a superfluid. They have bec…
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…
Multi-color broadband visible light source via three-dimensional GaN hexagonal annular microstructures
Young-Ho Ko, Jie Song, Benjamin Leung +2
Broadband visible light emitting, three-dimensional hexagonal annular microstructures with InGaN/GaN multiple quantum wells (MQWs) are fabricated via selective-area epitaxial growt…
