Paper Abstract
The transmission spectrum characteristic of two-segment polarization maintaining fibers Sagnac interferometer was investigated and simulated in detail and a temperature-insensitive pressure or strain sensing technology was proposed. An experimental hybrid Sagnac interferometer was built and the solid core polarization maintaining photonic crystal fiber was taken as the sensing probe. The side pressure sensitive coefficients and the temperature crosstalk drift were measured and compared. The experimental results show that the side pressure sensitive coefficient was ~0.2877 nm/N and the temperature drift was less than 0.1 pm/°C.
