Abstract

In this work, the LPG-assisted fibre Michelson modal interferometer is studied as a sensing structure for environmental refractive index, temperature and liquid level when coherence addressing and heterodyne interrogation are considered. The effects on measurand sensitivity of the order of the cladding mode excited by the LPG, of the degree of etching of the sensing fibre and of the fibre type used are investigated.
