Long Period Fiber Grating in Eccentric Core Single Mode Fiber

Not Accessible

Your library or personal account may give you access


Long period fiber gratings (LPFGs) were inscribed in an eccentric core single mode fiber (ECF) by a high frequency CO2 laser. The coupled-mode theory is used to analyze the coupling characteristics of the ECF-LPFG. Furthermore, the sensing properties of the LPFG in the ECF, including bending, temperature, and strain have been investigated experimentally. The maximum bending sensitivity 4.997 nm/ m−1 is obtained. The temperature and strain sensitivities of the ECF-LPFG are 59.3 pm/°C within a temperature range of 30°C - 90°C and 0.9 pm/με in the range of 0 με - 938 με.
