A vectorial magnetometer utilising a microstructured optical fibre Bragg grating infiltrated by a ferrofluid

摘要

There has been an increased interest in the infiltration of microstructured optical fibres (MOFs) using liquid or solid matrices of nano-tailored physical properties, for the development of photonic devices which exhibit new sensing and switching functionalities [1, 2]. Recently, we infiltrated ferrofluids inside MOF Bragg gratings demonstrating a novel in-fibre actuator [3].
