6. Conclusions

Currently, fiber-optic sensors do not occupy a leading position in the measurement system market. However, the continuous development of technologies, including fiber-optics, makes such devices more competitive and provides consumers with the advantages that traditional measurement systems cannot give. This, in turn, expands their scope. In this paper, our focus was on fiber-optic temperature sensors, namely, sensors with amplitude modulation of light. These sensors are just one of a wide variety of modern fiber-optic devices. In our previous work, which was briefly presented in Section 4, we used ChVS materials as a temperature-sensitive element for a fiber-optic temperature sensor. Further studies have shown the possibility of using A3B5 crystals as a temperature-sensitive element also. Section 5 presents the possibility of using such semiconductor materials on the example of GaP:Zn crystals. The temperature dependence shown in Figure 9 confirms that A3B5-type semiconductor materials can be used as a temperaturesensitive element of a fiber-optic sensor.
