Observation of Brillouin Spin-Orbit Interaction in a Silica Optical Nanofiber
Résumé
Spin-orbit interaction (SOI), whereby spin and orbital features of a
particle or a wave affect each other, is a ubiquitous phenomenon in many
branches of physics, including among others, optics and acoustics [1].
In optics, it has long been known that light carries both orbital
angular momentum (OAM) and spin angular momentum (SAM), related to
wavefront rotation and circular polarization, respectively, and that
they can become coupled by SOI while conserving the overall angular
momentum [1]. In acoustics, SOI has been recently reported using elastic
spin and angular momenta of transverse acoustic beams [2].
