Optics Letters
|November 2, 2013
Summary
We demonstrate a novel method to achieve a significant spin Hall effect of light (SHEL) using near-field dipole interactions and enhanced energy transfer. This technique leverages plasmonic platforms for substantial spin-orbit coupling effects in photons.
Area of Science:
- Optics and Photonics
- Quantum Optics
- Plasmonics
Background:
- The spin Hall effect of light (SHEL) is crucial for spin-dependent optical phenomena.
- Achieving large SHEL in nonparaxial conditions remains a challenge.
- Understanding spin-orbit coupling in light-matter interactions is essential.
Purpose of the Study:
- To introduce a new method for obtaining large spin Hall effect of light (SHEL) in nonparaxial settings.
- To explore the role of dipole-dipole interaction initiated energy transfer (FRET) in SHEL.
- To investigate the enhancement of SHEL using plasmonic platforms.
Main Methods:
- Utilizing the near field of dipoles, encompassing both homogeneous and evanescent plane waves.
- Basing SHEL on Förster Resonance Energy Transfer (FRET) between dipoles.
- Enhancing FRET-mediated SHEL through resonant surface plasmons (SPs) on metal films.
Main Results:
- Demonstrated a significant spin Hall effect of light (SHEL) in nonparaxial situations.
- Observed the conversion of σ(+) photons to σ(-) photons due to inherent spin-orbit coupling.
- Reported very large SHEL values mediated by resonant surface plasmons.
- Presented explicit results for SHEL on metal films and analyzed the impact of SP splitting.
Conclusions:
- The proposed method effectively generates large SHEL in nonparaxial scenarios.
- Plasmonic enhancement of FRET is a viable route to achieve significant spin-orbit coupling effects in light.
- The study provides insights into SHEL phenomena on metal films and the influence of surface plasmon properties.

5.2K
Edwin H. Hall, in the year 1879, devised an experiment that could be used to identify the polarity of the predominant charge carriers in a conducting material. From a historical perspective, this experiment was the first to demonstrate that the charge carriers in most metals are negative.

01:27π Electron Effects on Chemical Shift: Overview
1.5K
An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0,...

3.5K
The spin state of an NMR-active nucleus can have a slight effect on its immediate electronic environment. This effect propagates through the intervening bonds and affects the electronic environments of NMR-active nuclei up to three bonds away; occasionally, even farther. This phenomenon is called spin–spin coupling or J-coupling. Coupling interactions are mutual and result in small changes in the absorption frequencies of both nuclei involved. While nuclei of the same element are involved...

8.9K
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

01:03Atomic Nuclei: Nuclear Spin State Overview
1.9K
NMR-active nuclei have energy levels called 'spin states' that are associated with the orientations of their nuclear magnetic moments. In the absence of a magnetic field, the nuclear magnetic moments are randomly oriented, and the spin states are degenerate. When an external magnetic field is applied, the spin states have only 2 + 1 orientations available to them. A proton with = ½ has two available orientations. Similarly, for a quadrupolar nucleus with a nuclear spin value of one, the...
