“…Certainly, the PCF has unique optical properties and improved feature which is not in the conventional optical fibers. Such properties of PCF are high birefringence [20], flexibility in design [21], insensitivity to electromagnetic radiation [22][23][24], and high polarization maintaining property [25,26]. A single mode PCF is preferred for replacing bulk optical components in FOG [21,27].…”

A size reduced cladding layer of highly Birefringent photonic crystal fiber (PCF) that is suitable for fiber optic gyroscope application is proposed in this paper. A pair of minimized and enlarged air holes in the innermost layer of PCF is responsible for high birefringence and enlarged outer layer air holes are responsible for low confinement loss. The optimized geometrical parameters for this novel PCF are chosen so as to ensure high birefringence and low confinement loss. Fabrication of this proposed PCF is simplified by reducing the cladding layers. Obtained birefringence of this PCF is about 6.1 × 10−4 and the confinement loss is about 2.8 × 10−4 dB km−1.

“…Bergh constructed all components of IFOG with single continuous optical fiber [5]. Zuoming Sun uses polarization-maintaining photonic crystal fiber in IFOG to lower the thermal sensitivity of birefringence [6]. Since the first demonstration of IFOG in 1976 [1], many optimization schemes for signal processing have been presented.…”

Presented in this paper is a novel digital demodulation method for fiber-optic interferometric sensors. The method controls the modulation depth at π/2 radians and uses only five key points sampling values every modulation period. Both an automatic accurate sampling method and a modulation depth control method are introduced. Fewer resources are needed for the calculation processes to obtain the phase shift. High speed A/D converter is not necessary, which results in significant reduction of the manufacturing cost of fiber-optic interferometric sensors. A bias stability of 0.64 deg h −1 (i.e. 2.23 µrad) is demonstrated after using this method on an interferometric fiber-optic gyroscope (IFOG) based on the Sagnac effect.
