A Novel Wavelength Demodulation Method Using Twisted High Birefringence Fiber

摘要：

The mathematical model of twisted high birefringence fiber was established through theoretical analysis. a novel FBG wavelength demodulation method was put forward, by using the twisted high birefringence fiber. The numerical simulation and the experiments were carried out to the system. The standard cosine relationship was observed between the output intensity of polarization analyzer and the twist angle for the signal light with different wavelengths. When the twist angle of the high birefringence fiber is 0 and π/2, the output intensity ratio of the system presents the linear relationship with the wavelength approximately. The experiment shows that system is in agreement very well with theoretical analysis to demodulate guasi-linearly FBg wavelength shift in range of about 10 nm.
