Transparent matte surfaces enabled by asymmetric diffusion of white light
Hongchen Chu, Xiang Xiong, Nicholas X. Fang +5
The traditional wisdom for achieving transparency is to minimize disordered scattering within and on the surface of materials, so as to avoid translucency. However, the lack of dis…
Optimal nanoparticle forces, torques, and illumination fields
Yuxiang Liu, Lingling Fan, Eunnie Lee +3
A universal property of resonant subwavelength scatterers is that their optical cross-sections are proportional to a square wavelength, , regardless of whether they are plasmo…
Non-intuitive Computational Optimization of Illumination Patterns for Maximum Optical Force and Torque
Yoonkyung E. Lee, Owen D. Miller, M. T. Homer Reid +2
This paper aims to maximize optical force and torque on arbitrary micro- and nano-scale objects using numerically optimized structured illumination. By developing a numerical frame…
Ultrafast fluorescent decay induced by metal-mediated dipole-dipole interaction in two-dimensional molecular aggregates
Qing Hu, Dafei Jin, Sang Hoon Nam +4
Two-dimensional molecular aggregate (2DMA), a thin sheet of strongly interacting dipole molecules self-assembled at close distance on an ordered lattice, is a fascinating fluoresce…
Quantum-Spillover-Enhanced Surface-Plasmonic Absorption at the Interface of Silver and High-Index Dielectrics
Dafei Jin, Qing Hu, Daniel Neuhauser +6
We demonstrate an unexpectedly strong surface-plasmonic absorption at the interface of silver and high-index dielectrics based on electron and photon spectroscopy. The measured ban…
Tunable light-matter interaction and the role of hyperbolicity in graphene-hBN system
Anshuman Kumar, Tony Low, Kin Hung Fung +2
Hexagonal boron nitride (hBN) is a natural hyperbolic material which can also accommodate highly dispersive surface phonon-polariton modes. In this paper, we examine theoretically…
