Analytical mode normalization and resonant state expansion for optical fibers - an efficient tool to model transverse disorder
S. Upendar, I. Allayarov, M. A. Schmidt +1
We adapt the resonant state expansion to optical fibers such as capillary and photonic crystal fibers. As a key requirement of the resonant state expansion and any related perturba…
How to calculate the pole expansion of the optical scattering matrix from the resonant states
T. Weiss, E. A. Muljarov
We present a formulation for the pole expansion of the scattering matrix of open optical resonators, in which the pole contributions are expressed solely in terms of the resonant s…
Circularly polarized lasing in chiral modulated semiconductor microcavity with GaAs quantum wells
A. A. Demenev, V. D. Kulakovskii, C. Schneider +7
We report the elliptically, close to circularly polarized lasing at and 1.522 eV from an AlAs/AlGaAs Bragg microcavity with 12 GaAs quantum wells in the active reg…
White Paper on Light Sterile Neutrino Searches and Related Phenomenology
M. A. Acero, C. A. Argüelles, M. Hostert +169
This white paper provides a comprehensive review of our present understanding of experimental neutrino anomalies that remain unresolved, charting the progress achieved over the las…
Controlling circular polarization of light emitted by quantum dots using chiral photonic crystal slab
S. V. Lobanov, S. G. Tikhodeev, N. A. Gippius +9
We study the polarization properties of light emitted by quantum dots that are embedded in chiral photonic crystal structures made of achiral planar GaAs waveguides. A modification…
Large Quantum Delocalization of a Levitated Nanoparticle using Optimal Control: Applications for Force Sensing and Entangling via Weak Forces
T. Weiss, M. Roda-Llordes, E. Torrontegui +2
We propose to optimally control the harmonic potential of a levitated nanoparticle to quantum delocalize its center-of-mass motional state to a length scale orders of magnitude lar…
Quasinormal mode solvers for resonators with dispersive materials
P. Lalanne, W. Yan, A. Gras +16
Optical resonators are widely used in modern photonics. Their spectral response and temporal dynamics are fundamentally driven by their natural resonances, the so-called quasinorma…
Resonant-state expansion for open optical systems: Generalization to magnetic, chiral, and bi-anisotropic materials
E. A. Muljarov, T. Weiss
The resonant-state expansion, a recently developed powerful method in electrodynamics, is generalized here for open optical systems containing magnetic, chiral, or bi-anisotropic m…
Emission properties of an oscillating point dipole from a gold Yagi-Uda nanoantenna array
S. V. Lobanov, T. Weiss, D. Dregely +3
We investigate numerically the interaction of an oscillating point dipole with a periodic array of optical Yagi-Uda nanoantennas in the weak coupling limit. A very strong near-fiel…
Damage-free single-mode transmission of deep-UV light in hollow-core PCF
F. Gebert, M. H. Frosz, T. Weiss +5
Transmission of UV light with high beam quality and pointing stability is desirable for many experiments in atomic, molecular and optical physics. In particular, laser cooling and…
Influence of disorder on a Bragg microcavity
S. G. Tikhodeev, E. A. Muljarov, W. Langbein +3
Using the resonant-state expansion for leaky optical modes of a planar Bragg microcavity, we investigate the influence of disorder on its fundamental cavity mode. We model the diso…
