Topology-Enabled Switchable Unidirectional Radiative Band in a Bilayer Photonic Crystal
Zhiyi Yuan, Vytautas Valuckas, Yuhao Wang +6
Controlling how an open photonic system exchanges energy with its environment-and in particular how it radiates into the far field-is a cornerstone of non-Hermitian wave physics an…
Hybridization of Non-Hermitian Topological Interface Modes
Yuhao Wang, Hai-Chau Nguyen, Zhiyi Yuan +5
We propose and experimentally demonstrate the hybridization of radiating topological interface states, analogous to Jackiw-Rebbi states but in gain media with radiation fields. Thi…
Micrometer-resolution fluorescence and lifetime mappings of CsPbBr nanocrystal films coupled with a TiO grating
Viet Anh Nguyen, Linh Thi Dieu Nguyen, Thi Thu Ha Do +15
Enhancing light emission from perovskite nanocrystal (NC) films is essential in light-emitting devices, as their conventional stacks often restrict the escape of emitted light. Thi…
Dual-resonance nanostructures for colour down-conversion of colloidal quantum emitters
Son Tung Ha, Emmanuel Lassalle, Xiao Liang +9
Linear colour conversion is a process where an emitter absorbs a photon and then emits another photon with either higher or lower energy, corresponding to up- or down conversion, r…
Near-Unity Emitting, Widely Tailorable and Stable Exciton Concentrators Built from Doubly Gradient 2D Semiconductor Nanoplatelets
Xiao Liang, Emek G. Durmusoglu, Maria Lunina +11
The strength of electrostatic interactions (EI) between electrons and holes within semiconductor nanocrystals profoundly impact the performance of their optoelectronic systems, and…
An efficient neural optimizer for resonant nanostructures: demonstration of highly-saturated red silicon structural color
Ronghui Lin, Vytautas Valuckas, Thi Thu Ha Do +4
Freeform nanostructures have the potential to support complex resonances and their interactions, which are crucial for achieving desired spectral responses. However, the design opt…
Room-temperature strong coupling in a single photon emitter-dielectric metasurface system
T. Thu Ha Do, Milad Nonahal, Chi Li +5
Single-photon sources with high brightness and long coherence time are promising qubit candidates for quantum technology. To this end, interfacing emitters with high-finesse caviti…
Hybrid Dielectric-Plasmonic Nanoantenna with Multiresonances for Subwavelength Photon Sources
Pavel A. Dmitriev, Emmanuel Lassalle, Lu Ding +7
The enhancement of the photoluminescence of quantum dots induced by an optical nanoantenna has been studied considerably, but there is still significant interest in optimizing and…
Lasing action in single subwavelength particles supporting supercavity modes
Vasilii Mylnikov, Son Tung Ha, Zhenying Pan +4
On-chip light sources are critical for the realization of fully integrated photonic circuitry. So far, semiconductor miniaturized lasers have been mainly limited to sizes on the or…
Control of LED Emission with Functional Dielectric Metasurfaces
Egor Khaidarov, Zhengtong Liu, Ramon Paniagua-Dominguez +8
The improvement of light-emitting diodes (LEDs) is one of the major goals of optoelectronics and photonics research. While emission rate enhancement is certainly one of the targets…
Phase-only transmissive spatial light modulator based on tunable dielectric metasurface
Shi-Qiang Li, Xuewu Xu, Rasna Maruthiyodan Veetil +3
Rapidly developing augmented reality (AR) and 3D holographic display technologies require spatial light modulators (SLM) with high resolution and viewing angle to be able to satisf…
A Metalens with Near-Unity Numerical Aperture
Ramon Paniagua-Dominguez, Ye Feng Yu, Egor Khaidarov +8
The numerical aperture (NA) of a lens determines its ability to focus light and its resolving capability. Having a large NA is a very desirable quality for applications requiring s…
Generalized Brewster-Kerker effect in dielectric metasurfaces
Ramon Paniagua-Dominguez, Ye Feng Yu, Andrey E. Miroschnichenko +8
Polarization is one of the key properties defining the state of light. It was discovered in the early 19th century by Brewster, among others, while studying light reflected from ma…
