Abstract
Article history: Received 30 Jul. 2021 Received in revised form 01 Oct. 2021 Accepted 19 Oct. 2021 Available online 08 Nov. 2021 A compact temperature measuring device using a weakly coupled multi-core fibre in the Michelson interferometer structure is proposed and experimentally demonstrated. The device is manufactured by an easy and simple splicing approach which consists of a multicore fibre segment and an in-fibre coupler. In-fibre coupler is made of a cascaded singlemode fibre and multi-core fibre balls. It enhances the interference phenomenon of light energy between the central core and the outer cores of a multi-core fibre. The sensor shows a high quality fringe visibility of about 14–18 dB in the wavelength spectrum. Multi-core structure presents multi-path interferences and exhibits a maximum temperature sensitivity of 70.6 pm/°C in the range of 20–90°C with an insensitive response to the refractive index in the range of 1.334 to 1.354. The device has the advantages of compact size, easy manufacturing, and it solves cross-sensitivity between temperature and refractive index making it an authentic real-time temperature monitoring solution.
期刊介绍：
Opto-Electronics Review is peer-reviewed and quarterly published by the Polish Academy of Sciences (PAN) and the Association of Polish Electrical Engineers (SEP) in electronic version. It covers the whole field of theory, experimental techniques, and instrumentation and brings together, within one journal, contributions from a wide range of disciplines.
