Influence of random surface deformations on the resonance frequencies and quality factors of optical cavities and plasmonic nanoparticles
Philip Trøst Kristensen, Thomas Kiel, Kurt Busch +1
Surface deformations of optical cavities and plasmonic nanoparticles are inevitable in nanophotonics. The random morphology changes of different realizations modify the associated…
Numerical evaluation of Casimir forces using the discontinuous Galerkin time-domain method
Carles Martà Farrà s, Bettina Beverungen, Philip Trøst Kristensen +2
We present a time-domain scheme for computing Casimir forces within the Maxwell stress tensor formalism, together with a specific realization using the finite-element-based discont…
Strong coupling between a dielectric nanocavity and a monolayer transition metal dichalcogenide
F. Schröder, P. Wyborski, M. Xiong +6
We demonstrate strong coupling between light in a dielectric nanocavity with deep sub-wavelength confinement and excitons in a monolayer of molybdenum ditelluride. Avoided crossing…
Confocal polarization tomography of dielectric nanocavities
Frederik Schröder, Martin P. van Exter, Meng Xiong +4
We employ polarization tomography to characterize the modal properties of a dielectric nanocavity with sub-wavelength mode confinement. Our analysis of reflection spectra shows tha…
Omnidirectional gradient force optical trapping in dielectric nanocavities by inverse design
Beñat Martinez de Aguirre Jokisch, Benjamin Falkenberg Gøtzsche, Philip Trøst Kristensen +3
Optical trapping enables precise control of individual particles of different sizes, such as atoms, molecules, or nanospheres. Optical tweezers provide free-space omnidirectional o…
