Abstract

A mode interferometer coated with polydimethylsiloxane (PDMS) film based on photonic crystal fiber (PCF) is embedded into the fiber ring laser (FRL) sensing system for temperature and relative humidity measurement. High optical signal to noise ratio (OSNR) of ~54 dB, narrow 3 dB bandwidth of ~0.26 nm, and high-quality factor Q of 6×10³ were obtained, which indicate that the designed FRL system has ability to realize the measurement of environmental parameters with high resolution and accuracy and has potential application in remote monitoring of temperature. As the temperature increased from 35 °C to 115 °C, the spectral response has wavelength blue-shifts trend. The average temperature sensitivity of temperature sensor based on PCF is 90 pm/°C with small error bar and excellent linear correlation coefficient of 0.992. The average temperature sensitivity of temperature sensor based on PCF is 89 pm/℃ during the cooling process, revealing the proposed sensor has excellent reversibility. In addition, the sensor is insensitive to the change of relative humidity. Furthermore, the stability of temperature sensor based on PCF was experimentally demonstrated and analyzed. The maximal dip wavelength shifts of the peaks at 45 °C and 95 °C were 0.074 and 0.075 nm, respectively, within 3 hours. Besides, the FRL temperature sensor based on PCF has simple structure, excellent reversibility, repeatability, and stability. Therefore, the proposed FRL temperature sensor based on PCF has a great potential in practical applications where the high measurement precision and accuracy is required such as chemical reaction.
