Topologically protected second-harmonic generation via doubly resonant high-order photonic modes
Yafeng Chen, Zhihao Lan, Jensen Li +1
Topology-driven nonlinear light-matter effects open up new paradigms for both topological photonics and nonlinear optics. Here, we propose to achieve high-efficiency second-harmoni…
Optical Brewster metasurfaces exhibiting ultra-broadband reflectionless absorption and extreme angular-asymmetry
Huiying Fan, Jensen Li, Yun Lai +1
Impedance mismatch between free space and absorptive materials is a fundamental issue plaguing the pursue of high-efficiency light absorption. In this work, we design and numerical…
One-sided destructive quantum interference from an exceptional point-enabled metasurface
Hong Liang, Kai Ming Lau, Wai Chun Wong +3
We propose the concept of one-sided quantum interference based on non-Hermitian metasurfaces.By designing bianisotropic metasurfaces with a non-Hermitian exceptional point, we show…
Ultra-broadband reflectionless Brewster absorber protected by reciprocity
Jie Luo, Hongchen Chu, Ruwen Peng +3
The Brewster's law predicts zero reflection of p-polarization on a dielectric surface at a particular angle. However, when loss is introduced into the permittivity of the dielectri…
Optical Forces in Coupled Chiral Particles
Kah Jen Wo, Jie Peng, Madhava Krishna Prasad +3
Structural chirality can induce counter-intuitive optical forces due to inherent symmetry properties. While optical forces on a single chiral particle in the Rayleigh regime have b…
Two-dimensional phase-space picture of the photonic crystal Fano laser
Piotr M. Kamiński, Samel Arslanagić, Jesper Mørk +1
The recently realized photonic crystal Fano laser constitutes the first demonstration of passive pulse generation in nanolasers [Nat. Photonics , 81-84 (2017)]. We…
