First Demonstration of Multicore Fiber Long Period Gratings using Femtosecond Laser Direct Inscription Technique

We demonstrate long period gratings (LPGs) on multicore fibers using femtosecond laser direct writing technique. In experiment, we succeeded in independent LPG fabrication at arbitrary cores with a coupling efficiency as high as 90%.
