Abstract
A highly sensitive twist sensor without temperature cross sensitivity based on tapered single mode-thin core-single mode fiber offset structure is proposed and experimentally demonstrated. The two parameters mentioned above can be measured simultaneously without cross sensitivity. The twist sensitivity of 0.12dB/° is achieved by tracking power variation of the resonant wavelength, and the wavelength shift of the spectrum is ±0.01nm. The temperature sensitivity of 0.12nm/°C can be achieved by wavelength demodulation, and the power fluctuation of the spectrum is ±0.015dB. Therefore, the twist and temperature can be detected by the power and wavelength demodulation method, respectively.
