Abstract
A weight sensor with a polarization maintaining photonic crystal fiber (PCF) is proposed and investigated by experimentally. The sensor system consists of a 3 dB fiber coupler, a half-wave plate, and light source. Wavelength shift induced by weight acting on the polarization maintaining PCF was measured. Two types of sensor patterns, circle type and straight type, were implemented and evaluated. The sensitivity of straight line type was 680 pm/kg and the circle type was 270 pm/kg, respectively. The both types of sensors have a good sensitivity and good linearity in the wide range.
