Birefringence treatment of non-ideal optical microfibre coils for continuous Faraday rotation

Birefringence treatment of non-ideal optical microfibre coils for continuous Faraday rotation
A flexible technique to periodically perturb the evolution of differential phase in birefringent optical microfiber is proposed. This conceptual demonstration offers a simple yet effective solution to rectify non-ideal microfiber coil sensor heads for high-performance current sensing.

Introduction:
The rise of optical microfiber technology [1] has opened up a new lineage of current sensing. Optical current sensors employing optical microfibers (OM) based on the Faraday Effect have shown their potential for ultra-fast current detection in ultra-small geometries [2–4]. However, as with conventional current sensors, the problem of birefringence [5,6] still persists. Spun optical microfiber was previously proposed and demonstrated [7]. It offered improvements in the current responsivity at the expense of increased fabrication time and resources. In this Letter, we propose a post-fabrication technique to achieve the same goal, but with considerably lower fabrication complexity.

Abstract

A flexible technique to periodically perturb the evolution of differential phase in birefringent optical microfiber is proposed. This conceptual demonstration offers a simple yet effective solution to rectify non-ideal microfiber coil sensor heads for high-performance current sensing.

Introduction:
The rise of optical microfiber technology [1] has opened up a new lineage of current sensing. Optical current sensors employing optical microfibers (OM) based on the Faraday Effect have shown their potential for ultra-fast current detection in ultra-small geometries [2–4]. However, as with conventional current sensors, the problem of birefringence [5,6] still persists. Spun optical microfiber was previously proposed and demonstrated [7]. It offered improvements in the current responsivity at the expense of increased fabrication time and resources. In this Letter, we propose a post-fabrication technique to achieve the same goal, but with considerably lower fabrication complexity.
