Abstract :
Summary form only given. We describe the design methodology of geometric apodization and the fabrication of the apodized phase mask for UV-written fiber gratings. Concerning the two first diffraction orders used for UV exposure, the transmitted power is determined by the zero-order transmission, which is in turn determined by the variation of groove depth and ridge duty cycle. The simulated spectra for the zero-order output from a rectangular grating with a fixed ridge duty cycle shows that the position of the minimum zero-order transmission shifts with changing groove depth.
