Abstract: |
This invention relates to large chromatic dispersion Brag photon transistor fiber, which belongs to fiber communication system chromatic dispersion compensation technique field and is characterized by the following: the said fiber core is air hole; the cover layer is the air hole distributed along circle along the radius direction with axis of fiber, wherein there is silicon dioxide medium between each air hole; the said cover layer is removed with one deflection formed by silicon dioxide, wherein the deflection area is enough for fiber core to form non-symmetric couple with large effective refractive rate difference to form larger wave guide chromatic dispersion. |
