Limits to superweak amplification of beam shifts
Open accessAbstract
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 with superweak measurements in quantum theory. Particularly strong enhancements can be expected close to angles at which no light is transmitted for fixed initial and final polarizations. We derive a formula for the angular and spatial shifts at such angles (which includes the Brewster angle), and we show that their maximum size is limited by higher-order terms from the reflection coefficients occurring in the Artmann shift formula.

A similar interaction between the IOAM and EOAM occurs for vortex beams in inhomogeneous media, causing l-dependent transverse shifts at medium inhomogeneities (orbital-Hall effect).
“A quite similar interaction between the IOAM and EOAM (vortex and trajectory) occurs for vortex beams in inhomogeneous media 18,64,90- 95 . In this case, beams experience -dependent transverse shifts at the medium inhomogeneities.”
From Spin–orbit interactions of light (2015) · cites this paper as [90]
The discussion on p. 3 describes a postselected shift of a reflected beam and notes that the chosen polarizations produce an optical vortex. It does not address IOAM–EOAM interaction, vortex-beam propagation in inhomogeneous media, or ℓ-dependent transverse shifts at inhomogeneities (searched those terms and orbital-Hall effect).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
