Observation of the Inherent Chiral Smith-Purcell Effect via Symmetry Breaking
Juan-Feng Zhu, Fei Chen, Jun-Xuan Chen +9
The Smith-Purcell effect arises when charged particles move near a periodic structure, emitting radiation. Conventional approaches for generating chiral Smith-Purcell radiation rel…
Enabling Highly Efficient Infrared Silicon Photodetectors via Disordered Metasurfaces with Upconversion Nanoparticles
Wei Chen, Shutao Zhang, Chongwu Wang +12
Silicon photodetectors are highly desirable for their CMOS compatibility, low cost, and fast response speed. However, their application the infrared (IR) is limited by silicon's in…
Unidirectional Chiral Emission via Twisted Bi-layer Metasurfaces
Dmitrii Gromyko, Shu An, Sergey Gorelik +8
Controlling and channelling light emissions from unpolarized quantum dots into specific directions with chiral polarization remains a key challenge in modern photonics. Stacked met…
Silicon Nanoantenna Mix Arrays for a Trifecta of Quantum Emitter Enhancements
Zhaogang Dong, Sergey Gorelik, Ramón Paniagua-Dominguez +9
Dielectric nanostructures have demonstrated optical antenna effects due to Mie resonances. Preliminary investigations on dielectric nanoantennas have been carried out for a trifect…
Engineering Perovskite Emissions via Optical Quasi-Bound-States-in-the-Continuum
Evelin Csányi, Yan Liu, Soroosh Daqiqeh Rezaei +14
Metal halide perovskite quantum dots (PQDs) have emerged as promising materials due to their exceptional photoluminescence (PL) properties. A wide range of applications could benef…
Miniaturizing Color-Sensitive Photodetectors via Hybrid Nanoantennas towards Sub-micron Dimensions
Jinfa Ho, Zhaogang Dong, Hai Sheng Leong +10
Digital camera sensors utilize color filters on photodiodes to achieve color selectivity. As color filters and photosensitive silicon layers are separate elements, these sensors su…
Coupling Spin Defects in Hexagonal Boron Nitride to Titanium Oxide Ring Resonators
Milad Nonahal, Chi Li, Febiana Tjiptoharsono +7
Spin-dependent optical transitions are attractive for a plethora of applications in quantum technologies. Here we report on utilization of high quality ring resonators fabricated f…
Schrodinger's Red Pixel by Quasi Bound-State-In-Continuum
Zhaogang Dong, Lei Jin, Soroosh Daqiqeh Rezaei +9
While structural colors are ubiquitous in nature, saturated reds are mysteriously absent. Hence, a longstanding problem is in fabricating nanostructured surfaces that exhibit refle…
Photonic Bound-States-in-the-Continuum Observed with an Electron Nanoprobe
Zhaogang Dong, Zackaria Mahfoud, Ramón Paniagua-Domínguez +8
Bound-states-in-the-continuum (BIC)is a wave-mechanical concept that generates resonances with vanishing spectral linewidths. It has many practical applications in Optics, such as…
