High-dimensional spatial mode sorting and optical circuit design using multi-plane light conversion
Hlib Kupianskyi, Simon A. R. Horsley, David B. Phillips
Multi-plane light converters (MPLCs) are an emerging class of optical device capable of converting a set of input spatial light modes to a new target set of output modes. This oper…
Microwave Demonstration of Purcell Effect Enhanced Radiation Efficiency
L. D. Stanfield, A. W. Powell, S. A. R. Horsley +2
We experimentally demonstrate a Purcell effect-based design technique for improved impedance matching, and thus enhanced radiation efficiency from a small microwave emitter. Using…
Removing grazing incidence reflection with half-bound states and non-Hermitian systems
Dean A. Patient, Simon A. R. Horsley
Grazing incidence waves incident onto a surface will almost always be completely reflected. Here, we focus on removing reflection at grazing incidence, adopting the factorisation m…
Designing Metasurfaces to Manipulate Antenna Radiation
James R Capers, Stephen J Boyes, Alastair P Hibbins +1
Designer manipulation of light at the nanoscale is key to several next-generation technologies, from sensing to optical computing. One way to manipulate light is to design a materi…
Inverse Design in the Complex Plane: Manipulating Quasi-Normal Modes
James R Capers, Dean A Patient, Simon A R Horsley
Utilising the fact that the frequency response of a material can be decomposed into the quasi-normal modes supported by the system, we present two methods to directly manipulate th…
Designing Multi-functional Metamaterials
J. R. Capers, S. J. Boyes, A. P. Hibbins +1
The ability to design passive structures that perform different operations on different electromagnetic fields is key to many technologies, from beam-steering to optical computing.…
Quantum-classical correspondence in spin-boson equilibrium states at arbitrary coupling
Federico Cerisola, Marco Berritta, Stefano Scali +3
The equilibrium properties of nanoscale systems can deviate significantly from standard thermodynamics due to their coupling to an environment. For the generalised -angled spin-…
Tutorial: Macroscopic QED and vacuum forces
S. A. R. Horsley
This tutorial introduces the theory of macroscopic QED, where a Hamiltonian is found that represents the electromagnetic field interacting with a dispersive, dissipative material.…
Tutorial: Topology, waves, and the refractive index
S. A. R. Horsley
This tutorial is divided into two parts: the first examines the application of topology to problems in wave physics. The origins of the Chern number are reviewed, where it is shown…
