Recent advances in interferometry using suspended core fibres

In this paper, it is presented a brief review of the sensing applications using suspended core fibres. Since the first publication, several authors have studied their properties and possible applications in engineering. Due to their geometry, the great potential in optical sensing is in bio and gas sensing. Recently, with the possibility of inscribing Bragg grating structures on these fibres, it is possible to use them for other applications. Finally, this paper reviews the recent works with suspended core fibres for interferometry.
