Polarization optics of twisted single-mode fibers

Ulrich, R., Simon, A.·1979·Applied Optics

Abstract

In twisted single-mode optical fibers the polarization of light is affected by an elastooptically induced optical activity and by a modification of any linear birefringence present. These effects are discussed theoretically and demonstrated experimentally. The activity/twist ratio is alpha/tau approximately 0.13 ... 0.16 universally in weakly guiding silica fibers. Twisted fibers may be used as polarization rotators. A fiber with a +/-68 degrees double twist operates as a fast/slow mode interchanger, suitable for delay equalization.

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.
