Abstract

A temperature sensor was demonstrated and fabricated by coating thermosensitive film around a fiber coupler. Based on the multicladding equivalent method, the coated fiber coupler was simplified to a conventional one. With the high thermo-optical coefficient of organic–inorganic solgel material, a good sensing result was achieved. The range of temperature measured is from 50 ° C to 100 ° C . The resonant wavelength has a shift of about 25 nm . A sensitivity of 0.17 nm / ° C is achieved. With the advantages of having a simple structure and being unaffected by the instability of the light source, the proposed fiber coupler temperature sensor will find wide applications.
