Abstract

To produce a well-designed grating containing the required chirp and apodization characteristics, a numerical matrix of grating polygon points readable in the electron-beam writing machine was generated by a dedicated C-program. Within this matrix, the size of the grating ridges varied linearly along the grating axis, while the periodicity also varied due to chirping. This geometrical apodization phenomenon was first discovered and used in the phase-mask design to preserve the bandwidth of UV-written fiber gratings.
