Left-right asymmetry in an optical nanofiber
N.I. Petrov
TL;DR
This paper demonstrates a symmetry breaking effect in optical nanofibers where left- and right-handed circularly polarized light experience different transmissions due to spin-to-spin angular momentum conversion caused by tensor interactions.
Contribution
It reveals a novel left-right asymmetry in optical nanofibers arising from tensor interactions, highlighting a new mechanism for polarization-dependent transmission.
Findings
Left-right asymmetry in transmission for circular polarizations
Spin-to-spin angular momentum conversion observed
Asymmetry caused by tensor interactions in the fiber
Abstract
Symmetry breaking effect for left- and right-handed circularly polarized light beams propagating in a rotationally symmetric graded-index optical fiber is presented. It is shown that a left-right asymmetry manifested as an unequal transmission for opposite circular polarizations occurs due to spin-to-spin angular momentum conversion caused by tensor interaction.
