Geometric phases of light: insights from fibre bundle theory
C. M. Cisowski, J. B. Götte, S. Franke-Arnold
Geometric phases are ubiquitous in physics; they act as memories of the transformation of a physical system. In optics, the most prominent examples are the Pancharatnam-Berry phase…
On the conservation of helicity in a chiral medium
Frances Crimin, Neel Mackinnon, Jörg B. Götte +1
We consider the energy and helicity densities of circularly polarised light within a lossless chiral medium, characterised by the chirality parameter . A form for the helicity d…
Instantaneous modulations in time-varying complex optical potentials
Armen G. Hayrapetyan, S. P. Klevansky, Joerg B. Goette
We study the impact of a spatially homogeneous yet non-stationary dielectric permittivity on the dynamical and spectral properties of light. Our choice of potential is motivated by…
Eigenpolarizations for Giant Transverse Optical Beam Shifts
Jörg B. Götte, Wolfgang Löffler, Mark R. Dennis
We show how careful control of the incident polarization of a light beam close to the Brewster angle gives a giant transverse spatial shift on reflection. This resolves the long-st…
Limits to superweak amplification of beam shifts
Jörg B. Götte, Mark R. Dennis
The magnitudes of beam shifts (Goos-Hänchen and Imbert-Fedorov, spatial and angular) are greatly enhanced when a reflected light beam is postselected by an analyzer, by analogy wit…
Are Fresnel filtering and the angular Goos-Hänchen shift the same?
Jörg B. Götte, Susumu Shinohara, Martina Hentschel
The law of reflection and Snell's law are among the tenets of geometrical optics. Corrections to these laws in wave optics are respectively known as the angular Goos-Hänchen shift…
The analogy between optical beam shifts and quantum weak measurements
Mark R Dennis, Jörg B Götte
We describe how the notion of optical beam shifts (including the spatial and angular Goos-Hänchen shift and Imbert-Federov shift) can be understood as a classical analogue of a qua…
Generalized shifts and weak values for polarization components of reflected light beams
Jörg B Götte, Mark R Dennis
The simple reflection of a light beam of finite transverse extent from a homogenous interface gives rise to a surprisingly large number of subtle shifts and deflections which can b…
Paraxial and nonparaxial polynomial beams and the analytic approach to propagation
Mark R Dennis, Joerg B Goette, Robert P King +2
We construct solutions of the paraxial and Helmholtz equations which are polynomials in their spatial variables. These are derived explicitly using the angular spectrum method and…
On the dragging of light by a rotating medium
J. B. Goette, S. M. Barnett, M. Padgett
When light is passing through a rotating medium the optical polarisation is rotated. Recently it has been reasoned that this rotation applies also to the transmitted image (Padgett…
