摘要：
A novel fiber sensor based on photonic crystal fiber (PCF) for simultaneous measurement of temperature and humidity is proposed. The PCF is filled with alcohol, which is sensitive to temperature. And it is coated with graphene oxide (GO), which is sensitive to humidity. In the range of 10 degrees C-70 degrees C, the highest temperature sensitivity of the three interference valleys can reach up to 0.182 nm/degrees C. Similarly, in the range of 30%-70%, the highest humidity sensitivity is 0.109 nm/%RH. This configuration features the advantages of reliable repeatability, strong stability, and it is ideal for environmental detection.
