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
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
## Abstract Phase sampling and phase shift techniques are introduced in a uniform fiber Bragg grating structure to achieve a multiβbandpass filter with ultranarrow transmission bandwidth. A pair of dualβbandpass transmission windows are opened at 1542.32, 1542.36, and 1542.66, 1542.71 nm, respectiv
