Raman-probing the local ultrastrong coupling of vibrational plasmon-polaritons on metallic gratings
Rakesh Arul, Kishan Menghrajani, Marie S. Rider +3
Strong coupling of molecular vibrations with light creates polariton states, enabling control over many optical and chemical properties. However, the near-field signatures of stron…
Molecular Strong Coupling and Cavity Finesse
Kishan S. Menghrajani, Adarsh B. Vasista, Wai Jue Tan +3
Molecular strong coupling offers exciting prospects in physics, chemistry and materials science. Whilst attention has been focused on developing realistic models for the molecular…
Theory of strong coupling between molecules and surface plasmons on a grating
Marie S Rider, Rakesh Arul, Jeremy J Baumberg +1
The strong coupling of molecules with surface plasmons results in hybrid states which are part molecule, part surface-bound light. Since molecular resonances may acquire the spatia…
Strong Coupling of Multimolecular Species to Soft Microcavities
Adarsh B Vasista, William L Barnes
Can we couple multiple molecular species to soft-cavities? The answer to this question has relevance in designing open cavities for polaritonic chemistry applications. Due to the d…
Effect of molecular absorption and vibrational modes in polariton assisted photoemission from a layered molecular material
Adarsh B Vasista, Kishan S Menghrajani, William L Barnes
The way molecules absorb, transfer, and emit light can be modified by coupling them to optical cavities. The extent of the modification is often defined by the cavity-molecule coup…
Differential molecule-cavity mode coupling in soft-cavities
Adarsh B Vasista, William L Barnes
The way molecules absorb, transfer, and emit light can be dramatically modified by coupling them to optical cavities. The extent of the modification is often defined by the cavity-…
Molecular monolayer strong coupling in dielectric soft microcavities
Adarsh B Vasista, William L Barnes
We report strong coupling of a monolayer of J-aggregated dye molecules to the whispering gallery modes of a dielectric microsphere at room temperature. We systematically studied th…
Classical antennae, quantum emitters, and densities of optical states
William L Barnes, Simon A R Horsley, Willem L Vos
We provide a pedagogical introduction to the concept of the local density of optical states (LDOS), illustrating its application to both the classical and quantum theory of radiati…
Nanoscale design of the local density of optical states
Sandro Mignuzzi, Stefano Vezzoli, Simon A. R. Horsley +3
We propose a design concept for tailoring the local density of optical states (LDOS) in dielectric nanostructures, based on the phase distribution of the scattered optical fields i…
Manipulating type-I and type-II Dirac polaritons in cavity-embedded honeycomb metasurfaces
Charlie-Ray Mann, Thomas J. Sturges, Guillaume Weick +2
Pseudorelativistic Dirac quasiparticles have emerged in a plethora of artificial graphene systems that mimic the underlying honeycomb symmetry of graphene. However, it is notorious…
Particle plasmons: Why shape matters
William L. Barnes
Simple analytic expressions for the polarizability of metallic nanoparticles are in wide use in the field of plasmonics, but their origins are not obvious. In this article, express…
Absence of Anderson localization in certain random lattices
Wonjun Choi, Cheng Yin, Ian R. Hooper +2
We report on the transition between an Anderson localized regime and a conductive regime in a 1D scattering system with correlated disorder. We show experimentally that when long-r…
Evidence of Excitonic Optical Tamm States using Molecular Materials
S. Núñez-Sánchez, M. López-García, M. M. Murshidy +6
We report the first experimental observation of an Excitonic Optical Tamm State supported at the interface between a periodic multilayer dielectric structure and an organic dye-dop…
Strong coupling between surface plasmon polaritons and emitters
P. Törmä, W. L. Barnes
In this review we look at the concepts and state-of-the-art concerning the strong coupling of surface plasmon-polariton modes to states associated with quantum emitters such as exc…
