Twist Sensor Based on Long Period Grating and Tilted Bragg Grating Written in Few-Mode Fibers
A twist sensor based on a few-mode long period grating (LPG) and a tilted fiber Bragg grating (TFBG) is proposed and demonstrated. The LPG, inscribed in a step index few-mode fiber by a CO<sub>2</sub> laser, is utilized to excite the LP<sub>11</sub> core mode. The followed TF...
