The paper presents a method of fabrication of a fiber-optic temperature sensor based on an end-face Fabry-Perot interferometer made in the form of a polymer “bridge”, a part of which is a sensitive element of the sensor. The main material for creation of the sensitive part is UV-curable resin, transparent for optical and near-infrared range. The performance of the sensor was tested using an optical spectrum analyzer. The peaks and dips visible on the reflection spectrum of the broadband radiation source indicated the correct operation of the Fabry-Perot interferometer, and their displacement when the sample temperature changes allowed to measure the sensitivity of the proposed type of sensor. As a result of this work it is shown that the sensitivity of the developed sensor is higher than that of existing analogs, and its dimensions allow its application in biomedical applications and critical temperature measurements.References
