A new exposure scheme for fabricating apodised ΓΏber Bragg gratings by the use of a uniform phase mask and a Gaussian beam laser is demonstrated. Average refractive index is kept nearly constant along the grating to derive a side lobe suppression of 20 dB in the shorter wavelength. This scheme allows
We demonstrate the generation of fiber Bragg gratings in As2S3 fibers using a 633 nm HeNe laser and a 0/ Γ1 phase mask. In a 20-micron core fiber, 17-dB reflection was observed at 1545 nm with a linewidth of 0.18 nm. This method is more robust than the transverse holographic method previously demons
This paper reports on the fabrication process of phase mask for fiber grating printing. The masks are produced by Electron Beam Lithography (EBL) and Reactive Ion Etching (RIE). A special writing strategy is used in order to reduce the stitching errors. RIE with CI-IF3 will be discussed. Finally mor
