Coherent Plasmonic Absorption in the Femtosecond Regime
Venkatram Nalla, Xu Fang, João Valente +2
Dissipation of electromagnetic energy through absorption is a fundamental process that underpins phenomena ranging from photovoltaics to photography, analytical spectroscopy, photo…
Nanoimprinted topological laser in the visible
Qiang Zhang, Rui Duan, Yutian Ao +6
Nanoimprint lithography (NIL) is a widely used high-throughput fabrication technique for photonic devices, yet its reliability is often compromised by the inevitable imperfections…
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…
Affine nonmagnetic transformation optics and its application to a practical bending adapter design
Hongyi Xu, Baile Zhang, Tianyuan Yu +2
One of the bottlenecks that limit the transition of transformation-optics devices from concepts to practical use is the non-unit magnetic permeability generally required from a mat…
Controlling photonic spin Hall effect via exceptional points
Xinxing Zhou, Xiao Lin, Zhicheng Xiao +4
The photonic spin Hall effect (SHE), featured by a spin-dependent transverse shift of an impinging optical beam driven by its polarization handedness, has many applications includi…
Experimental demonstration of an ultra-thin three-dimensional thermal cloak
Hongyi Xu, Xihang Shi, Fei Gao +2
We report the first experimental realization of a three-dimensional thermal cloak shielding an air bubble in a bulk metal without disturbing external thermal flux. The cloak is mad…
Wide-angle giant photonic spin Hall effect
Zhihao Chen, Yu Chen, Yaodong Wu +5
Photonic spin Hall effect is a manifestation of spin-orbit interaction of light and can be measured by a transverse shift λof photons with opposite spins. The precise measurement…
