High Sensitivity Strain Sensor Using Long-Period Fiber Grating Inscribed in the Graded Index Few-Mode Fiber

We present a long-period fiber grating inscribed in graded index few-mode fiber utilizing CO 2 laser technology. The near filed intensity distribution and strain sensing characteristics of the proposed device were investigated experimentally.
