Abstract
An optical filter and reflector, it includes: A single-mode optical fiber, its cross section includes a core and cladding layer surrounding the core. And the single-mode optical fiber includes plural separated compound areas along the axial direction. In which, The compound areas include Bragg grating located in core area and a medium, which refraction is closed to core area of single-mode optical fiber. In which, the compound area has a plane closed to core area. The plane is formed by removing portion-cladding layer at side of compound area. And the medium is located on the plane.Therefore, the Bragg condition of compound area is changed by changing the refraction of medium.
