Abstract
There is provided a device and method for forming optical fiber anti-symmetric long period gratings by microbending. In the optical fiber grating forming device, a laser system emits a CO laser beam, a lens focuses the CO laser beam on an optical fiber in a predetermined width, an optical fiber support fixes both ends of the optical fiber and imparts tensile strain to the optical fiber, and a controller controls the intensity of the CO laser beam, the focusing distance of the lens, and the tensile force applied by the optical fiber support.
