Fiber Bragg grating with a waveguide fabricated in no-core fiber and multimode fiber

A new, to the best of our knowledge, method of fabricating a fiber Bragg grating (FBG) in no-core fiber (NCF) and multimode fiber (MMF) is proposed and demonstrated, achieved by writing an in-fiber waveguide before the grating inscription. This approach makes it possible to fabricate the FBG in NCF ...
