Abstract

The novel microstructured optical fibres (MOF) with suspended core design guiding linear and quasi-circular polarized modes has been developed which demonstrates linear birefringence scalable in a range 5×10^-4 to 2×10^-2 by tuning the core size. The SPUN type of this MOF exhibits a high magneto-optical effect for sensitive coil diameter of 5 mm and shows no degradation of performance, e.g. optical losses and magneto-optical sensitivity, for turns number of 10²÷10⁴. The transmission losses are 2÷4 dB/km and the magneto-optical sensitivity approaches the value of 70% of theoretical limit for small diameter coil. The potential applications of such MOF in gyro and optical current transformer will be discussed.
