Faraday rotation in tuned optical fibre coils

Faraday rotation in tuned optical fibre coils
Faraday rotation in tuned optical fibre coils
Compact devices based on Faraday rotation in optical fibres have not been developed because linear birefringence, either inherent to the fibre or induced by bending, acts to quench the rotation (circular birefringence). However, it was recently demonstrated that quenching can be largely overcome if the sense of the magnetic field alternates along the fibre in successive half-beat-length increments of the linear birefringence. In this paper we describe practical, easy-to-manufacture devices based on this principle.

Abstract

Compact devices based on Faraday rotation in optical fibres have not been developed because linear birefringence, either inherent to the fibre or induced by bending, acts to quench the rotation (circular birefringence). However, it was recently demonstrated that quenching can be largely overcome if the sense of the magnetic field alternates along the fibre in successive half-beat-length increments of the linear birefringence. In this paper we describe practical, easy-to-manufacture devices based on this principle.
