WebThe label often reflects the used fabrication method – for example, there are ruled gratings, holographic gratings and replicated gratings. While in most cases the grating surface is plane (plane gratings), there are also gratings with a curved (e.g. spherical convex or concave) surface. This can be advantageous, for example, for achieving ... WebJan 29, 2024 · In this paper, we demonstrate a narrow-linewidth tunable fiber laser based on laser-induced graphene (LIG) paper-heated fiber Bragg grating (FBG) with low voltage. A linewidth of less than 600 Hz is achieved by the combination of a piece of unpumped Er-doped fiber and an FBG.
